Couple of points to get u started
1) Clear Your project solution and rebuild your project
2) Restart your Visual studio instance and open your project freshly
After you clear project and reopen visual studio, if problem still continue, try delete the designer and regenerate it.

I'd like to have special fields with ASP.NET, I use ASP:TextBox for my login page. The idea is : when you are in a mobile device, it recognizes the field and purpose a special keyboard with only numbers (my login page uses only numbers)
I tested that, but it doesn't works :
<asp:TextBox CssClass="LoginTxtBox" ID="Txt_nom" runat="server" AutoCompleteType="Disabled" ForeColor="Black" MaxLength="20" Width="100%" Height="30px" TextMode="Number"></asp:TextBox>
"Number isn't a member of System.UI.WebControls.TextBoxMode"
I checked and Number is a member of this. I don't understand why I can't debug with that. (I can launch the website with IIS, no issue)
Thanks for your help !
could you try:
<asp:TextBox CssClass="LoginTxtBox" ID="Txt_nom" runat="server" AutoCompleteType="Disabled" ForeColor="Black" MaxLength="20" Width="100%" Height="30px" type="Number"></asp:TextBox>
changed "TextMode" into "type".
see more info here: http://mobiforge.com/design-development/html5-mobile-web-forms-and-input-types
this will help:
<asp:TextBox ID="Txt_nom" runat="server"></asp:TextBox>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" ControlToValidate="Txt_nom" runat="server" ErrorMessage="Only Numbers allowed" ValidationExpression="\d+"></asp:RegularExpressionValidator>
I hava a asp.net that I thought is going to have multiple forms.I put a asp panel and added the form to it and validators to controls everyting works.but if I try to put another panel and a form page become invalid.the reason I do this is because any attempt to postback data will trigger all validtors.I know that I can brake each form to each page.but for my design this seems silly.
what im looking for a way to have multiple forms in one page.
or have validators work only on certain situations.
or group validators to work if the button click only happen in the same panel where validators reside.
You cannot place more than one form tag in a single ASPX page. It is a limitation of ASP.Net Web Form.
However, you can fake it with ValidationGroup. For example -
<%-- Group One --%>
<asp:TextBox ID="TextBox1" runat="server"
ValidationGroup="One" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator1"
runat="server"
Display="Dynamic"
ValidationGroup="One"
ControlToValidate="TextBox1"
Text="Textbox one is required." />
<asp:Button runat="server" ID="Button1"
OnClick="Button1_Click"
Text="Submit"
ValidationGroup="One" />
<hr/>
<%-- Group Two --%>
<asp:TextBox ID="TextBox2" runat="server"
ValidationGroup="Two" />
<asp:RequiredFieldValidator ID="RequiredFieldValidator2"
runat="server"
Display="Dynamic"
ValidationGroup="Two"
ControlToValidate="TextBox2"
Text="Textbox two is required.." />
<asp:Button runat="server" ID="Button2"
OnClick="Button2_Click"
Text="Submit"
ValidationGroup="Two" />
Note: If you want multiple form tags in a single page, you might want to look at ASP.Net MVC.
I am having a bit of trouble with a dynamic asp.net FormView (within Insert.aspx.vb) in my ASP.NET LINQ to SQL Website. Here is the code for the FormView...
<asp:FormView runat="server" ID="FormView1" DataSourceID="DetailsDataSource" DefaultMode="Insert"
OnItemCommand="FormView1_ItemCommand" OnItemInserted="FormView1_ItemInserted" RenderOuterTable="false">
<InsertItemTemplate>
<table id="detailsTable" class="DDDetailsTable" cellpadding="6">
<asp:DynamicEntity runat="server" Mode="Insert" />
<tr class="td">
<td colspan="2">
<asp:LinkButton runat="server" CommandName="Insert" Text="Insert" />
<asp:LinkButton runat="server" CommandName="Cancel" Text="Cancel" CausesValidation="false" />
</td>
</tr>
</table>
</InsertItemTemplate>
</asp:FormView>
When this form is displayed in a browser, there are 5 user input controls, and two buttons (insert/cancel). But here in the code, I do not see any reference to the 5 user input controls, unless they are represented by this line of code...
<asp:DynamicEntity runat="server" Mode="Insert" />
First, am I correct in assuming that this line of code builds the user input controls dynamically?
And, my actual problem -- I need to set the Focus to the first of these input's upon page initialization. Basically when someone chooses to insert a new item and is sent to this page, I want them to be able to start typing right away, without the need to actually click in that textbox to begin. Any help would be greatly appreciated?
I was able to resolve my issue by adding a Search field via Code, and then using this in the Page_Load event...
If table.DisplayName = "Employees" Then
MultiSearchFieldSet.Visible = True
txbMultiColumnSearch.Focus()
I have an ASP.NET 4.0 web application where users upload videos to the server. I have a FileUpload control and 2 DropDownLists.
The user first selects a video to be uploaded from the FileUploadcontrol after that s/he selects a category from DropDownList1 (category list). After the user selects a category, I fill the second DropDownList with subcategories.
When I select a file to upload, and select a category from the DropDownList, the page disconnects from the server after postback. If I do the same scenario without selecting a file to be uploaded, I succesfully fill the second combo.
Here is my code :
<tr>
<td style="text-align: left;" class="style9" colspan="2">
<asp:Label ID="Label1" runat="server" Text="Video" Width="80px"></asp:Label>
<asp:FileUpload ID="FileUploadVideo" runat="server" ViewStateMode="Enabled" />
</td>
<td style="text-align: left;" class="style4">
<asp:Label ID="Label3" runat="server" Text="Category" Width="80px"></asp:Label>
<br />
<asp:DropDownList ID="cmbCategory" runat="server" AutoPostBack="True" OnSelectedIndexChanged="cmbCategory_SelectedIndexChanged">
</asp:DropDownList>
</td>
<td style="text-align: right;">
<asp:Label ID="Label6" runat="server" Text="Subcategory" Width="80px"></asp:Label>
<br />
<asp:DropDownList ID="cmbSubcategory" runat="server">
</asp:DropDownList>
</td>
</tr>
Any help would be appreciated.
Since you're uploading video, I imagine this is erroring out due to the file size. The default max file size for ASP.NET applications is 4MB. You can add something like this to the <system.web> section of your web.config to increase that deault:
<system.web>
<httpRuntime executionTimeout="240" maxRequestLength="20480" />
</system.web>
This allows, for instance, for a 20MB file to be uploaded.

I have an ASP.NET page developed in VS 2008. there is a text box and login button.Required fireld validator and Validtion Group controls are associate for validation.I wrote code for the Button click evenet handler too.But the Button click is not getting fired.There is no post back happening. Can any one tell me why ?
HTM lmarkup
<asp:TextBox ID="txtLoginPass" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" ControlToValidate="txtPassword" ValidationGroup="Login" ErrorMessage="Please enter password." runat="server" />
<asp:Button ID="btnLogin" runat="server" Text="Login"
onclick="btnLogin_Click" ValidationGroup="Login" />
Validators generate client side JavaScript which can prevent a postback if the required field is empty.
Is that exact code snippet? It didn't work at all - no such control as txtPassword.
Altough, this worked as expected:
<asp:TextBox ID="txtPassword" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" ControlToValidate="txtPassword" ValidationGroup="Login" ErrorMessage="Please enter password." runat="server" />
<asp:Button ID="btnLogin" runat="server" Text="Login"
onclick="btnLogin_Click" ValidationGroup="Login" />
I'm sure that you've got that correct in your code, so the problem must be somewhere else - could please post more code surrounding this snippet?
I expect that you have AutoPostBack="True" on one of your components. If so then remove that and your onclick should work on the button.
I had this same exact problem. The RequiredFieldValidator was working as expected when the textbox was empty, but the button click wasn't causing a postback when there was text. My problem? I was using the same validationgroup name in a separate user control. So make sure all of your validationgroup names are unique.
