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 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>
In the below code i have a grid view in which i have a textbox i am passing 0 and 1 to check box if it is 1 the checkbox to be checked.I tried but it is not working.Pls help me to solve the issue.
<asp:TemplateColumn HeaderText="Sales Price Ref" ItemStyle-Width="200px" HeaderStyle-VerticalAlign="Top">
<HeaderTemplate>
<asp:Label ID="lblSalesPriceRef" runat="server" Text="Sales Price"></asp:Label>
<br /><br />
<asp:TextBox runat="server" ID="txtSalesPriceRef" AutoPostBack="true" BorderStyle="Solid" BorderColor="#6495ED" BackColor="#B0C4DE" Height="20px" Width="90px" OnTextChanged="txtItem_TextChanged"></asp:TextBox>
</HeaderTemplate>
<EditItemTemplate>
<asp:CheckBox ID="ChSalesPriceRef" runat="server" Checked='<%#Eval("SalesPriceRef")=="1" ? true:false %>' />
<%-- <asp:TextBox ID="txtSalesPriceRef" Width="90px" runat="server" Text='<%#Eval("SalesPriceRef") %>'></asp:TextBox>--%>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="lblSalesPriceRef" runat="server" Text='<%# Convert.ToString(Eval("SalesPriceRef"))== "1" ? "True" :"False" %>' > </asp:Label>
</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'm using asp and have some textboxes where I want to set the value from code behind. The code below is wrapped inside an asp:DetailsView.
The Textbox I want to get and set value of is InsertItemTemplate with ID=strPositionsName
<asp:TemplateField HeaderText="Name" SortExpression="strPositionName">
<InsertItemTemplate>
<asp:TextBox ID="strPositionName" Width="380px" MaxLength="49" runat="server" Text='<%# Bind("strPositionName") %>'></asp:TextBox>
</InsertItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="Textbox1" Width="380px" MaxLength="49" runat="server" Text='<%# Bind("strPositionName") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Width="380px" Text='<%# Bind("strPositionName") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
I managed to get the value by:
var testName = ((TextBox)DetailsView1.FindControl("strPositionName")).Text;
So I tried using this:
((TextBox)DetailsView1.FindControl("strPositionName")).Text = "textboxvalue";
But it didn't work
Try Following Code
TextBox _txtPositionName=(TextBox)DetailsView1.FindControl("strPositionName");
if(_txtPositionName!=null)
_txtPositionName.Text="textboxvalue";
Not able to DataBound the Style attribute
Style='<%# Eval("LeftPadding","padding-left:{0}") %>'
Full Code
<asp:TemplateField HeaderText="Report Item" SortExpression="ReportItem">
<ItemTemplate>
<asp:Label Style='<%# Eval("LeftPadding","padding-left:{0}") %>' ID="lblReportItem"
runat="server" Text='<%# Eval("Caption") %>'></asp:Label>
</ItemTemplate>
<ItemStyle Width="350px" />
</asp:TemplateField>
But I can DataBound some other attributes even not a Standard HTML attribute, like below
<asp:Label StyleTemp='<%# Eval("LeftPadding","padding-left:{0}") %>' ID="lblReportItem"
runat="server" Text='<%# Eval("Caption") %>'></asp:Label>
What is the problem with Style ?
Got Answer :)
<asp:Label Style=<%# string.Format("padding-left:{0}px",Eval("LeftPadding")!=DBNull.Value? Convert.ToString(Eval("LeftPadding")): "0") %>
ID="lblReportItem" runat="server" Text='<%# Eval("Caption") %>'></asp:Label>
Tried by without giving the Single Quotes for the style attribute and used string.Format
Style=<%# string.Format("padding-left:{0}px",Eval("LeftPadding")!=DBNull.Value? Convert.ToString(Eval("LeftPadding")): "0") %>
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>
