you should be use TemplateField for display your checkbox:
<asp:TemplateField HeaderText="headerText">
<ItemTemplate>
// your image or text for display checked or not
<asp:Label ID="Label6" runat="server" Text='<%# Eval("isView")=="True"?"IS CHECKED":"NOT CHECKED" %>'></asp:Label>
</ItemTemplate>
<EditTemplate>
<asp:CheckBox DataField="isView" runat="server" />
</EditTemplate>
</asp:TemplateField>

DropdownList in Gridview not saving values

I have a gridview with a dropdownlist in one column in editing mode
The problem is that I can't save the selected value after edit and I can show the data from the field when I press edit.
I show some examples doing SelectedValue='<%# Bind("Category") %>' but the SelectedValue is unrecognizable.
The page is
<asp:TemplateField HeaderText="Category" SortExpression="Category">
<EditItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" DataTextField="Category" >
<asp:ListItem>1</asp:ListItem>
<asp:ListItem>2</asp:ListItem>
<asp:ListItem>3</asp:ListItem>
<asp:ListItem>4</asp:ListItem>
</asp:DropDownList>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("Category") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
When I use a textbox instead of the dtopdown then the values after editing are saved correctly
Any ideas?
Finally I found a solution to my problem.
In the templatefield I've select edit databindings and then in the SelectedValue I've select Custom Binding and put Bind("category")
Now it works

Setting value to hidden field in gridview

How to set ItemTemplate text value to combobox DataTextField instead of DataValueField

I have a telerik radgrid with a GridTemplateColumn as seen below in a C# ASP.NET 4.0 webform.
As you can see, in the EditItemTemplate I am using a RadComboBox with an id number for DataValueField and a human readable text for DataTextField.
My question is, how can I change the Text in my ItemTemplate to show the human readable value instead of the Id? The value Alias1 comes from the grid datasource and it is the Id.
Thank you for any help you can provide!
<telerik:GridTemplateColumn UniqueName="Alias1" Display="true" DataField="Alias1" HeaderText="Alias1" SortExpression="Alias1">
<ItemTemplate>
<asp:Label ID="lblField30" CssClass="text" runat="server" Text='<%# Bind("Alias1") %>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<telerik:RadComboBox ID="RadComboBox16" runat="server" Skin="Outlook" Height="150" DataSourceID="SqlDataSourceAliasOptions" DataTextField="aliasText" DataValueField="aliasid" SelectedValue='<%#Bind("Alias1") %>'>
</telerik:RadComboBox>
</EditItemTemplate>
</telerik:GridTemplateColumn>
You need to change ItemTemplate binding like this:
<ItemTemplate>
<asp:Label ID="lblField30" CssClass="text" runat="server" Text='<%# Eval("aliasText") %>'></asp:Label>
</ItemTemplate>
Of course your binded entity must have "aliasText" property. If you are binding something like DataTable make sure that contains "aliasText" column.

Gridview : Hyperlink and description in the same column cell

Apologies for the newbie question. My client wishes me to make a small change to the gridview on his http://www.flogitdonegal.com/SearchPage.aspx page.
Note the way the Title column is a hyperlink to view more information. This comes from a 'BriefDescription' field in the database.
How can I add 250 chars from the 'FullDescription' underneath the Title in the same cell, but I dont want it be a hyperlink.
Essentially it will be 2 fields coming into the same column.
Thanks in advance for all help.

If this is using a GridView you are most likely using a TemplateField as it is to display the HyperLink.
Within the ItemTemplate of the TemplateField you can specify an additional Label underneath using something as follows:
<asp:Label runat="server" id="FullDescLabel" Text='<%# DataBinder.Eval(Container.DataItem, "FullDescription") %>' />
You need to use the TemplateField and here is a tutorial that explains some of the other fields that GridView offers as well.
<asp:GridView ID="gvwCompounds" runat="server" DataSourceID="objItemsFromYourDB">
<Columns>
....
<asp:TemplateField>
<ItemTemplate HeaderText="Title">
<asp:HyperLink runat="server" ID="Hperlink1" NavigateUrl='<%# Eval("BriefDescriptionUrl") %>' Text='<%# Eval("BriefDescription") %>' />
<br />
<asp:Label runat="server" ID="Label1" Text='<%# Eval("FullDescription") %>' />
</ItemTemplate>
</asp:TemplateField>
....
</Columns>
</asp:GridView>

<asp:TemplateField Boxes Disappearing

I've got a text box that just disappeared. When I add another templateField anywhere on the page, this one bizarelly disappears. Anyone know what might be up?
<asp:TemplateField HeaderText="Summary" SortExpression="summary">
<ItemTemplate>
<asp:Label ID="lblSummary" runat="server" Text='<%# Bind("summary") %>'></asp:Label>
</ItemTemplate>
<ItemTemplate>
<asp:TextBox ID="txtSummary" TextMode="MultiLine" Width="500" Height="100" runat="server" Text='<%# Bind("summary") %>'></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>

I hope you don't take this wrong, and I mean no offense, but it seems like you're missing some of the basic concepts and need a good place to learn them.
Please check out the following article so that you fully understand how to use TemplateFields as opposed to a normal BoundField or a Command field. I think once you "get" it, your disappearing item issues will clear up because you'll be able to see it on your own.

You can't have more than one ItemTemplate in a TemplateField. You can have an EditItemTemplate and an ItemTemplate, though...
Edit - Added
The ItemTemplate shows when you're in normal display mode.
The EditItemTemplate shows when you're in edit mode
InsertItemTemplate shows when you're in Insert mode.
For any column in a GridView (or field in a FormView or field in a DetailsView) there can only be one TemplateField.
Within that TemplateField, there can only be one ItemTemplate, one EditItemTemplate, and one InsertItemTemplate (and not all three are required but all three are recommended.)
If you want the TextBox to show up next to the label in the normal non-edit mode, you would put the text box within the existing ItemTemplate as follows:
<ItemTemplate>
<asp:Label ID="lblSummary" runat="server" Text='<%# Bind("summary") %>'>
</asp:Label>
<asp:TextBox ID="txtSummary" TextMode="MultiLine" Width="500" Height="100" runat="server" Text='<%# Bind("summary") %>'>
</asp:TextBox>
</ItemTemplate>
However, the norm is to have the label when in read mode, and a text box when in edit or update mode like shown below:
<asp:TemplateField HeaderText="Summary" SortExpression="summary">
<ItemTemplate>
<asp:Label ID="lblSummary" runat="server" Text='<%# Bind("summary") %>'>
</asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtSummary" TextMode="MultiLine" Width="500" Height="100" runat="server" Text='<%# Bind("summary") %>'>
</asp:TextBox>
</EditItemTemplate>
<InsertItemTemplate>
<asp:TextBox ID="txtSummary" TextMode="MultiLine" Width="500" Height="100" runat="server" Text='<%# Bind("summary") %>'>
</asp:TextBox>
</InsertItemTemplate>
</asp:TemplateField>
You have multiple "ItemTemplate" declarations in there. There should be only one.
