I want to partially update data of this listview.
<asp:ListView ID="ListView_SoldItems" runat="server" OnItemDataBound="ListView_SoldItems_ItemDataBound" >
<ItemTemplate>
<uc1:SongUC runat="server" id="SongUC" />
</ItemTemplate>
</asp:ListView>
If it wasn't a listview I could have done this.
<asp:ScriptManager ID="ScriptManager1" runat="server" />
<asp:UpdatePanel runat="server" id="UpdatePanel" updatemode="Conditional">
<ContentTemplate>
<asp:ListView ID="ListView_SoldItems" runat="server" OnItemDataBound="ListView_SoldItems_ItemDataBound" >
<ItemTemplate>
<uc1:SongUC runat="server" id="SongUC" />
</ItemTemplate>
</asp:ListView>
</ContentTemplate>
</asp:UpdatePanel>
So what would be the solution for this?
I found it.
<asp:ListView ID="ListView_SoldItems" runat="server" OnItemDataBound="ListView_SoldItems_ItemDataBound" ClientIDMode="AutoID" >
Just had to add the ClientIDMode="AutoID" property to the Listview.

Here is my code:

I know that the snippet does not have a closing tag for some of the tags at the beginning of the snippet. The reason I left them out is because there is a lot of code between them and their closing tags. Besides, from what I can tell my problem is with the with either 1 line or another in this code snippet.
When I try to compile this to run the web app I get the following error:
TabContainer cannot have children of type
'System.Web.UI.WebControls.Button'.
The error highlights this line:
<ajaxToolKit:TabContainer ID="MedicaidDataSubTabContainer" runat="server">
But because the error states there can't be a button in the container I'm wondering if this line has something to do with it:
<asp:Button runat="server" ID="MedicaidData_Search" Text="Search" width="100px" />
I've looked at quite a few solutions online and they all say that the container needs runat="server" and an ID. As you can see both of these lines have those parts. Anyone have an idea of another solution I can try? Thanks in advance.
I think it's because you have content outside of a content template.
The outline should be
<ajaxToolkit:TabContainer ID="TabContainer1" runat="server" ActiveTabIndex="0">
<ajaxToolkit:TabPanel ID="TabPanel1" runat="server" HeaderText="TabPanel1">
<ContentTemplate>
Content1
</ContentTemplate>
</ajaxToolkit:TabPanel>
<ajaxToolkit:TabPanel ID="TabPanel2" runat="server" HeaderText="TabPanel2">
<ContentTemplate>
Content2
</ContentTemplate>
</ajaxToolkit:TabPanel>
</ajaxToolkit:TabContainer>
I am fetching data from DB and assign it to repeater.
When I click on button event it only goes to page load function but not to the required on-click event.
I am confused as to why this is happening.
And when I comment out repeater its working fine. I don't why it's not working with repeater in page load.
Aspx code:
<form runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server"></asp:ScriptManager>
<asp:UpdatePanel runat="server" pdateMode="Conditional" ChildrenAsTriggers="true" >
<asp:Button ID="Button2" runat="server" Text="Next Availabilities"
OnClick="Button2_Click" />
<asp:Repeater id="repeater1" runat="server">
<ItemTemplate>
<asp:Label ID="Label2" runat="server" Text=""><%# Eval("Time") %></asp:Label>
</ItemTemplate>
</asp:Repeater>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID ="Button3" EventName ="Click" />
<asp:AsyncPostBackTrigger ControlID ="Button2" EventName ="Click" />
</Triggers>
</asp:UpdatePanel>
</form>
In your UpdatePanel:
Correct pdateMode to UpdateMode
Remove ChildrenAsTriggers="true"
Add starting tag of <ContentTemplate>
Assign id ID="UpdatePanel1"
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
I have GridView inside UpdatePanel and UpdateMode of the UpdatePanel is set to conditional.
Gridview contains asp:CheckBox as TemplateField and rest of the columns are boundfields which are dynamically created.
Checbox AutoPostBack is set to true and I update a datatable (which is inside session) based on checkbox value.
Here is markup:
<asp:GridView ID="ObjList" runat="server" CssClass="ObjList" AutoGenerateColumns="false" OnRowDataBound="ObjList_RowDataBound" AutoGenerateSelectButton="false" AllowPaging="False">
<Columns>
<asp:TemplateField HeaderText=" ">
<HeaderTemplate>
<asp:CheckBox AutoPostBack="true" ID="chkAll" runat="server" OnCheckedChanged="HeaderChk_Changed" />
<asp:HiddenField ID="LinkNumIndexHead" runat="server" Value="-1" />
</HeaderTemplate>
<ItemTemplate>
<asp:CheckBox AutoPostBack="true" ID="chkRow" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "Selection")%>'
OnCheckedChanged="ChkRow_OnCheckChange" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
In Deployed version only:
Whenever user click 2 or more checkboxes in fast speed. Postback of first checkbox fires and rest of checkboxes get unchecked. How can I control this behavior?
When Local IIS is running:
Postback of every checkbox fires.
In Firebug debugging it is noticed that Postback of first checkbox takes quite a time.
Please tell me how can I avoid this situation.
Try this
<asp:GridView ID="ObjList" runat="server" CssClass="ObjList" AutoGenerateColumns="false"
OnRowDataBound="ObjList_RowDataBound" AutoGenerateSelectButton="false" AllowPaging="False">
<Columns>
<asp:TemplateField HeaderText=" ">
<HeaderTemplate>
<asp:UpdatePanel runat="server">
<ContentTemplate>
<asp:CheckBox AutoPostBack="true" ID="chkAll" runat="server" OnCheckedChanged="HeaderChk_Changed" />
</ContentTemplate>
</asp:UpdatePanel>
<asp:HiddenField ID="LinkNumIndexHead" runat="server" Value="-1" />
</HeaderTemplate>
<ItemTemplate>
<asp:UpdatePanel ID="UpdatePanel5" runat="server">
<ContentTemplate>
<asp:CheckBox AutoPostBack="true" ID="chkRow" runat="server" Checked='<%# DataBinder.Eval(Container.DataItem, "Selection")%>'
OnCheckedChanged="ChkRow_OnCheckChange" />
</ContentTemplate>
</asp:UpdatePanel>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I have a gridview with a checkbox in first column. I set checkbox property of autopostback="true". The gridview is inside the updatepanel. When checkbox is checked i want to make one panel as visible, which panel is outside the update panel. I check the code with check point, which is go through the code, but its not working. Can any one help me?..
Thanks in advance.
My code is here for your reference...
HTML Code:
<asp:Panel ID="ploperation" runat="server" CssClass="plop" Visible="False">
<asp:LinkButton ID="lbtnasspam" runat="server" CssClass="panelbtn" Font-Names="Calibri"
Font-Size="14px" Font-Underline="False" OnClick="lbtnasspam_Click">Report As Spam</asp:LinkButton>
</asp:Panel>
<asp:UpdatePanel ID="up" runat="server">
<ContentTemplate>
<asp:GridView ID="gvmail" runat="server" AllowPaging="True" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkchild" runat="server" AutoPostBack="true" OnCheckedChanged="chkchild_CheckedChanged"/>
</ItemTemplate>
<ItemStyle Width="15px" />
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
C# Code:
protected void chkchild_CheckedChanged(object sender, EventArgs e)
{
ploperation.Visible = true;
}
You can use initializeRequest - this event is raised when an asynchronous post back occurs(When you check the checkbox in your gridview it initiates an async postback because it's inside an update panel).
Just change ploperation to a div instead of <asp:Panel and you can use javascript to show/hide it:
<form id="form1" runat="server">
<asp:ScriptManager ID="ScriptManager1" runat="server">
</asp:ScriptManager>
<script type="text/javascript">
var prm = Sys.WebForms.PageRequestManager.getInstance();
prm.add_initializeRequest(initializeRequest);
function initializeRequest(sender, args) {
document.getElementById('ploperation').style.display = 'block';
}
</script>
<asp:UpdatePanel ID="up" runat="server">
<ContentTemplate>
<asp:GridView ID="gvmail" runat="server" AllowPaging="True" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkchild" runat="server" AutoPostBack="true" />
</ItemTemplate>
<ItemStyle Width="15px" />
</asp:TemplateField>
</Columns>
</asp:GridView>
</ContentTemplate>
</asp:UpdatePanel>
<div id="ploperation" style="display:none;" runat="server">
<asp:LinkButton ID="lbtnasspam" runat="server" CssClass="panelbtn" Font-Names="Calibri"
Font-Size="14px" Font-Underline="False" OnClick="lbtnasspam_Click">Report As Spam</asp:LinkButton>
</div>
</form>
Alternatively you can stick to the way you've done it, just place <asp:Panel inside UpdatePanel -> ContentTemplate
update panel does partial page loading....
check link
so if you want to show your panel than include it also in your update panel.
Put the UpdatePanel on the control you want to change, not on the GridView. Do not forget to Reference the GridView on the Triggers section. For example, if you want to change a label text use the following code:
<asp:UpdatePanel ID="up" runat="server">
<ContentTemplate>
<asp:Label ID="Label1" runat="server" Text="" />
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="gvmail" />
</Triggers>
</asp:UpdatePanel>
<asp:GridView ID="gvmail" runat="server" AllowPaging="True" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:CheckBox ID="chkchild" runat="server" AutoPostBack="true" OnCheckedChanged="chkchild_CheckedChanged"/>
</ItemTemplate>
<ItemStyle Width="15px" />
</asp:TemplateField>
</Columns>
</asp:GridView>
I have added two update panels to my page. I'm trying to update the first panel but not the second. The second panel contains validation controls which seem to be kicking in no matter what I try.
Code
<asp:ToolkitScriptManager runat="server" ID="ScriptManager" />
<asp:UpdatePanel ID="updatePnl" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:label ID="NoConsignments" runat="server" ForeColor="red" />
<br />
<asp:TextBox ID="StartDate" runat="server" /> <asp:TextBox ID="EndDate" runat="server" /> <asp:Button ID="Dates" OnClick="btDates" runat="server" Text="Search" />
<asp:calendarextender ID="Calendarextender2" targetcontrolid="StartDate" Format="dd/MM/yyyy" runat="server"></asp:calendarextender>
<asp:calendarextender ID="Calendarextender3" targetcontrolid="EndDate" Format="dd/MM/yyyy" runat="server"></asp:calendarextender>
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="Dates" />
</Triggers>
</asp:UpdatePanel>
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional">
<ContentTemplate>
</ContentTemplate>
</asp:UpdatePanel>
I've left out some of the middle code of there is alot. If you would like any more code please let me know.
Am I missing something? or is this not the way that update panels should be used?
Thanks you so much for any help you can provide
I would guess that the validation controls in the second UpdatePanel are firing their client-side validation methods (so the update panel isn't posting back, which is correct).
You might be able to get around this by using the ValidationGroup property - assign the validation controls in the first update panel to one validation group (e.g. "ValidationGroupA"), and the validation controls in the second update panel to another validation group.
I haven't used UpdatePanels for a while, and you haven't included the mark up for the validators in the second panel.
However it looks to me like you might not be adding groups to your validation see this tutorial
e.g.:
<body>
<form id="form1" runat="server">
<div>
<asp:TextBox ID="TextBox1" runat="server" ValidationGroup="First"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ValidationGroup="First" ErrorMessage="TextBox1 should not be blank"
ControlToValidate="TextBox1"/>
<asp:Button ID="Submit1" runat="server" ValidationGroup="First"
Text="Submit 1"/>
<asp:TextBox ID="TextBox3" runat="server" ValidationGroup="Second"/>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server"
ErrorMessage=" TextBox3 should not be blank"
ControlToValidate="TextBox3" ValidationGroup="Second"/>
<asp:Button ID="Submit2" runat="server" ValidationGroup="Second"
Text="Submit 2"/>
</div>
</form>
</body>
Hope this helps and I haven't missed the point.
You have to specify ValidationGroups for your Buttons and Validators, f.e. Panel1 for your Searchbutton and Panel2 for your Validators in second UpdatePanel.
<asp:Button ID="Dates" ValidationGroup="Panel1" runat="server" Text="Search" />
....
<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
<ContentTemplate>
<asp:TextBox ID="TextBox1" runat="server" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
ValidationGroup="Panel2" ErrorMessage="RequiredFieldValidator"
ControlToValidate="TextBox1" />
</ContentTemplate>
</asp:UpdatePanel>
