I have a column that has an ImageButton. my database field has bit data type. I want when my record has true value in that column show True.jpg and my command become MakeFalse and when it has false value show False.jpg and my command become MakeTrue. How I can do this?Is it possible to do it with one TemplateField?
thanks
You could include two ImageButtons in a TemplateField and evaluate Visible from your bit_field
<asp:TemplateField HeaderText="YourField">
<ItemTemplate>
<asp:ImageButton runat="server" ImageUrl="True.jpg" Visible='<%# (bool)Eval("bit_field") %>' />
<asp:ImageButton runat="server" ImageUrl="False.jpg" Visible='<%# !(bool)Eval("bit_field") %>' />
</ItemTemplate>
</asp:TemplateField>
I'm not sure how you'd want your Command to tie in.
This is the remaining part of the above Brissles code
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False"
CommandName="Select" Text='<%#(bool)Eval("bit_field")? "Make False":"Make True" %>'>
</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>

The CommandField of my gridview looks like this:
<asp:CommandField ShowEditButton="true" ItemStyle-Width="70px" />
Clicking on "Edit" will show the "Update" and "Cancel" buttons like so:
Is there an easy way to change the position of those two buttons so that they look like this?
If you use TemplateField, and give the buttons a reserved CommandName (Edit, Update, Cancel, Delete) then you can give them any style and position in the GridView you want.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="true" OnRowDataBound="GridView1_RowDataBound">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Edit">Edit</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CommandName="Delete">Update</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
I want to use DropDownCheckBoxes control in EditItemTemplate of my TemplateField. When I put it in normal ItemTemplate - it works. But when DropDownCheckBoxes is in EditItemTemplate - it doesn't appears...
"Select" is the only word that appears in the place where should be my DDCB.
<asp:TemplateField>
<ItemTemplate>
<asp:Label runat="server" ID="lblTest" Text='<%# Bind("test") %>' />
</ItemTemplate>
<EditItemTemplate>
<asp:DropDownCheckBoxes ID="ddcbTest" runat="server"></asp:DropDownCheckBoxes>
</EditItemTemplate>
</asp:TemplateField>
Have you ever tried to use DropDownCheckBoxes in EditItemTemplate?
How can I add edit form row in Asp.NET GridView control like this RadGrid!
When I click on the Edit button, I want to add an edit form row under the edit button row.
Here my Grid
<asp:GridView ID="gvEG" runat="server" AutoGenerateColumns="False">
<Columns>
<asp:TemplateField>
<EditItemTemplate>
<asp:DropDownList runat="server" ID="ddlPersonnel" />
</EditItemTemplate>
<ItemTemplate>
//..
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<EditItemTemplate>
//..
</EditItemTemplate>
<ItemTemplate>
//..
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<EditItemTemplate>
<asp:LinkButton ID="lnkUpdate" runat="server" CommandName="Update" />
<asp:LinkButton ID="lnkCancel" runat="server" CommandName="Cancel" />
</EditItemTemplate>
<ItemTemplate>
<asp:LinkButton ID="lnkEdit" runat="server" CommandName="Edit" />
<asp:LinkButton ID="lnkDel" runat="server" CommandName="Delete" />
</ItemTemplate>
</asp:TemplateField>
</Columns>
<EditRowStyle></EditRowStyle>
</asp:GridView>
In your GridView attributes add AutoGenerateEditButton and a custom event handler for OnRowEditing like this:
<asp:GridView ID="gvEG" runat="server" AutoGenerateColumns="False" AutoGenerateEditButton="True" OnRowEditing="gvEG_RowEditing">
Then in your code-behind make a new event handler method called "gvEG_RowEditing". Have your method add a panel under the row that is being edited. Add the necessary fields to the panel as well as an update button. Create a click event handler for the update button and have it save all the fields to the database and then rebind the GridView.
I've got an Asp.Net GridView inside an UpdatePanel. It all works fine, except when one of the columns includes HTML special characters like < and >. The GridView is bound to a List<Entity> and the Entity class has a property Regex which is a System.Text.RegularExpressions.Regex.
At first I had this:
<asp:TemplateField HeaderText="RegEx">
<ItemTemplate>
<asp:Label ID="RegExLabel" runat="server" Text='<%#Eval("Regex") %>'
ToolTip='<%#Eval("Regex") %>' Width="102px" CssClass="Wrap" />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="RegExTextBox" runat="server" Text='<%#Eval("Regex") %>'
Width="98px" />
</EditItemTemplate>
</asp:TemplateField>
With a value of (?<capture>\d+) this displayed ?\d+ when not editing, and when editing this row I got a script error and the edit, update and cancel buttons no longer work.
Then I tried the answer in this question and had this:
<asp:TemplateField HeaderText="RegEx">
<ItemTemplate>
<asp:Label ID="RegExLabel" runat="server"
Text='<%#System.Web.HttpUtility.HtmlEncode(Eval("Regex").ToString()) %>'
ToolTip='<%#System.Web.HttpUtility.HtmlEncode(Eval("Regex").ToString()) %>'
Width="102px" CssClass="Wrap" />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="RegExTextBox" runat="server"
Text='<%#System.Web.HttpUtility.HtmlEncode(Eval("Regex").ToString()) %>'
Width="98px" />
</EditItemTemplate>
</asp:TemplateField>
This is slightly better, in that the tooltip and the non-editing version display correctly, but when I start editing I see: (?<capture>\d+) with the HTML Entities displayed raw. Does anyone know a way to encode the values (to stop the script error) while still displaying them correctly without the HTML entities in their raw state when editing?
<asp:TemplateField HeaderText="RegEx">
<ItemTemplate>
<asp:Literal Mode="Encode" ID="RegExLabel" runat="server" Text='<%#Eval("Regex") %>'
ToolTip='<%#Eval("Regex") %>' Width="102px" CssClass="Wrap" />
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="RegExTextBox" runat="server" Text='<%#Eval("Regex") %>'
Width="98px" />
</EditItemTemplate>
</asp:TemplateField>
and in the page directive add this ValidateRequest="false"
how to make a conformation on boundfield in gridview in delete ....event
As far as I understand you want to add confirmation on deleting in your grid, correct?
Here is a simple example of grid:
<asp:GridView runat="server"
<Columns>
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton runat="server"
CommandName="Delete"
OnClientClick='return confirm("Are you sure?");'
Text="Delete" />
</ItemTemplate>
</asp:TemplateField>
<!-- your bound fields here -->
</Columns>
</asp:GridView>
The trick is in adding client-side confirm to the OnClientClick property of the delete button.
Can you do something like this?
<asp:linkbutton id="btnDelete" runat="server" commandname="Delete" onclientclick="return confirm('Are you sure you want to delete this item?');"
text="Delete" />
