</ItemTemplate>
</asp:TemplateColumn>
YES you can achieve it by binding it to the checkbox
as
<asp:CheckBox ID="ChSalesPriceRef" runat="server" Checked='<%# Bind("SalesPriceRef")%>' Enabled="false" />
if you allow to change checkbox value then make enable=true

I have one Gridview with 5 columns including the edit column. When I click Edit I would like the last column EditItemTemplate Textbox 'The_Title' to take up the maximum width of the cell. It never does! (I can shrink the tbTitle with the Width attribute but not increase) I have tried many things including 'GridView1_RowDataBound'. What am I missing.
protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
for (int i = 0; i < e.Row.Cells.Count - 1; i++)
{
if (i == 4)
{
e.Row.Cells[i].Attributes.Add("style", "white-space:nowrap;padding:0px;margin:0px;width:500px");
}
}
}

Any clues would be appreciated. Thank You.
Using Browser developer tools, you should be able to inspect the resulting mark-up (HTML) for your text box and tinker with it to see what is causing the size restriction.
IE developer tools (F12) will show you the hierarchical (cascading) order where the width setting is being defined.
Tested your GridView. The TextBox tbTitle is 500 px wide, just as expected. There is probably some bootstrap or other css overwriting the width.
What happens if you add a class for it?
<EditItemTemplate>
<asp:TextBox ID="tbTitle" runat="server" CssClass="fullWidth" Text='<%# Bind("The_Title") %>'></asp:TextBox>
</EditItemTemplate>
.fullWidth {
width: 100% !important;
}
Or set it inline as !important. If that does not work then there is probably something else going on.
<asp:TextBox ID="tbTitle" runat="server" style="width: 100% !important" Text='<%# Bind("The_Title") %>'></asp:TextBox>
I want to make one of the data bound in my gridview uneditable or in my case, I want to make the textbox in edit mode in read only. here is what I have tried but not successful:
TextBox ProductImage = GridView1.Rows[e.RowIndex].FindControl("TextBox1") as TextBox;
ProductImage.ReadOnly = true;
and here is the aspx code:
asp:TemplateField HeaderText="ProductImage" SortExpression="ProductImage">
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Eval("ProductImage") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# Eval("ProductImage") %>' />
</ItemTemplate>
<ControlStyle Width="50px" />
</asp:TemplateField>
can someone help me out?
Have you tried setting ReadOnly to true in your aspx code?
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" ReadOnly="true" Text='<%# Eval("ProductImage") %>'/>
</EditItemTemplate>
Or you could use a Label instead of a TextBox
<asp:Label ID="Label1" runat="server" Text='<%# Eval("ProductImage") %>'/>
I have a nested grid. I would like to validate a dropdown control within the child grid when the user adds a record. But in a nested grid, the control IDs are not unique. If you have 2 parent rows and a nested grid under each parent the child grid controls will have the same ID. When I validate, the validation is checking all of the nested grids and not just the one that I am trying to add to.
This is the markup:
<asp:GridView ID="GroupGridView" runat="server" AutoGenerateColumns="False"
Caption="Group Information" CaptionAlign="Top" CssClass="grid"
ShowFooter="true" DataKeyNames="GroupID">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<a href="javascript:DivExpandCollapse('div<%# Eval("GroupID")%>');">
<img id="imgdiv<%# Eval("GroupID")%>" width="25px" border="0" src="Images/plus.png" /> </a>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="GroupID">
<ItemTemplate>
<asp:Label ID="uggvLblGroupID" runat="server" Text='<%# Bind("GroupID") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Group Name">

Regardless of which 'Add Member' button I click, the validation is triggered for all of the nested grids because the Validation Groups are not unique.
How can I uniquely identify the ValidationGroup for each nested grid?
Thanks.
UPDATE
The ValidationGroup identifier works when adding a member to the first nested group but not to subsequent nested grids. It seems it is still going thru all of the nested grids and not just the one from the 'Add' button you clicked.
//Access Validators and Buttons
RequiredFieldValidator RequiredFieldValidator1 = (RequiredFieldValidator)e.Row.FindControl("RequiredFieldValidator1");
RequiredFieldValidator RequiredFieldValidator2 = (RequiredFieldValidator)e.Row.FindControl("RequiredFieldValidator2");
RequiredFieldValidator RequiredFieldValidator3 = (RequiredFieldValidator)e.Row.FindControl("RequiredFieldValidator3");
Button Button = (Button)e.Row.FindControl("Button1");
//Assign validation group to controls.
RequiredFieldValidator1.ValidationGroup = "Gridview1" + e.Row.RowIndex.ToString();
RequiredFieldValidator2.ValidationGroup = "Gridview1" + e.Row.RowIndex.ToString();
RequiredFieldValidator3.ValidationGroup = "Gridview1" + e.Row.RowIndex.ToString();
Button.ValidationGroup = "Gridview1" + e.Row.RowIndex.ToString();
i have made a gridview which has many columns and the editmode , some are text and dropdown list are are working perfect .
How can i assign value to a Checkbox to make it Checked or Unchecked?
The value against which i want to do is Yes / No.
So i am having trouble doing this.
My Gridview: Just pasting portion of it as its too big.
<asp:TemplateField HeaderText="CUpdate">
<ItemTemplate >
<asp:Label ID="Label6" runat="server" Text='<%# Eval("CUpdate") %>' ></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID="txtCupdate" Text='<%# Eval("CUpdate") %>' ></asp:TextBox>
</EditItemTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText="Email">
<ItemTemplate >
<asp:Label ID="Label6" runat="server" Text='<%# Eval("Email") %>' ></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:CheckBoxList ID="checkEmail" runat="server">
<%--HOW TO MAKE THIS CHECKED OR UNCHECKED ? when i have values Yes / NO--%>
</asp:CheckBoxList>
</EditItemTemplate>
</asp:TemplateField>
Update
If i make the above as :
<EditItemTemplate>
<asp:CheckBoxList ID="checkEmail" selectedvalue='<%# Eval("Email") %>' runat="server">
<asp:ListItem Value="Yes">Yes</asp:ListItem>
</asp:CheckBoxList>
</EditItemTemplate>
In this case i do get checkbox checked when there us Yes , but in case on NO it wont run possible error as there is no value 'NO' to select in the checboxlist .Any solution.
Thank you
Your CheckBoxList needs to have all the posible values like so..
<asp:CheckBoxList ID="checkEmail" selectedvalue='<%# Eval("Email") %>' runat="server">
<asp:ListItem Value="Yes">Yes</asp:ListItem>
<asp:ListItem Value="No">No</asp:ListItem>
</asp:CheckBoxList>
Although i don't understand why you want to use a CheckBoxList instead of just 1 checkbox like so..
<asp:CheckBox runat="server" ID="checkEmail" Checked = '<%# Eval("Email").ToString().Equals("yes", StringComparison.OrdinalIgnoreCase) %>' />
me problem is next:
I have a DetailsView control with many editItemTemplates some work fine but i have one dont work's.
code here:
<asp:TemplateField HeaderText="Date" SortExpression="date">
<ItemTemplate>
<%#this.putDate(Eval("fecha")) %>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="date" runat="server" ></asp:TextBox>
<asp:CalendarExtender id="CE" runat="server" Format="dd/MM/yyyy"
PopupButtonID="calImg" TargetControlID="date">
</asp:CalendarExtender>
<asp:ImageButton id="calImg" runat="server" CommandName=""
ImageUrl="img/imgCal.gif" />
</EditItemTemplate>
</asp:TemplateField>
In view mode the information appear right but in edit mode after select new date with calendar and pres accept to update information, the data dont update. Any idea?
Thz!
Replace:
<asp:TextBox ID="date" runat="server" ></asp:TextBox>
With:
<asp:TextBox ID="date" runat="server" Text='<%# Bind("SelectedDate") %>'></asp:TextBox>
