C# - Datagrid Button Column - How To Bind A Function To A Button
Dec 25, 2010
Currently i have a datagrid view that displays names in the 1st columnnd in the 2nd column delete buttons.
This datagrid view already has bind data to a function so it can displays the names that are withint a xml file (first column is a hyperlink column).
But next i want to be able to delete the xml values that are in the first column.(by clicking on the delete button on the second column of it)
<name></name>
But how do i exactly bind a (delete) function to these buttons?
name1 btnDelete
name2 btnDelete
etc...

I have an aspx page with two buttons, one of the buttons has an OnClick attribute to a function that should be run when clicked. When the other button is clicked there is an if statement checking if the page is a postback, if it is then I run some statements that need to be run when that button is clicked. That postback button works fine. However, the other button, when it's clicked the function it's supposed to call never executes, and the statements inside if (Page.IsPostBack) get executed instead. What can I do to fix this? Is there a way to make the button that calls a function not do a Post back?

Let's say I have a DataGrid that looks something like:
<asp:DataGrid ID="SomeDataGrid"
runat="server">
<Columns>
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="Data"></asp:BoundColumn>
</Columns>
</asp:DataGrid>
In this Grid, I set the datasource to some collection that contains a public property called "Data" and do a databind(). Every works as expected.Now let's say I want to set the DataField attribute of the column to a public member, or a property, or some other thing I've computed. What is the easiest way to go about this without creating intermediate objects or adding public properties to the objects in the collection?So what I want to do is something like:
<asp:BoundColumn HeaderText="A Header" SortExpression="Sort" DataField="someMethod()"></asp:BoundColumn

I have a Data Grid View which display values from a SQL Query, and inside the data grid view I have two template fields one is Quantity and it is a text box and the other is Total Price and it is a label.
What I want to do is to insert a button called update and when I press this button the price Column should be multiplied by the quantity Column and the result should be displayed in the total Column.

I have a ButtonColumn in a DataGrid:
<asp:ButtonColumn HeaderText="Edit" ButtonType="PushButton" Text="Edit" />
How do I set it's CSS class?
The only way I can see to do it, is hooking to the RowDataBound event:
[Code]....
I just feel like there must be a neater way. What happens if I add/remove columns, I'll have to come back here and remember to change column 6...
I tried using a TemplateColumn and a usual asp:Button - This worked, but then clicking it did not fire the ItemCommand event of the grid which I need to fire.

I am trying to add a ModalPopup to a GridView, by adding a button in the data grid header:
<asp:GridView ID="GridViewTradeDetail" />
<Columns>
<asp:TemplateField HeaderText="B/S">
<HeaderTemplate>
<asp:Button ID="ButtonShowBuySellPopup" runat="server" Text="Set B/S" />
</HeaderTemplate>
<EditItemTemplate>
<asp:TextBox ID="TextBox1" runat="server" Text='<%# Bind("buy_sell") %>'></asp:TextBox>
</EditItemTemplate>
<ItemTemplate>
<asp:Label ID="Label1" runat="server" Text='<%# Bind("buy_sell") %>'></asp:Label>
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="trade_date" HeaderText="TD" />
</Columns>
</asp:GridView>
...
<asp:Panel ID="PanelBuySell" runat="server">
... panel content ...
</asp:Panel>
<ajaxToolkit:ModalPopupExtender ID="ModalPopupExtenderBuySell" runat="server"
TargetControlID="ButtonShowBuySellPopup" PopupControlID="PanelBuySell" />
<asp:Button ID="ButtonShowBuySellPopup" runat="server" Text="Set B/S" />
But I get an error that the ModalPopupExtender cannot find the button ButtonShowBuySellPopup (If I move the button out of the grid header it's OK).
How can I link the popup to a button (or better still, text link) in the header of a Gridiew?

I have basically something like this:
<asp:datagrid id="DGrid" runat="server" AutoGenerateColumns="false">
<asp:TemplateColumn HeaderText="Stuff">
<ItemTemplate>
<asp:PlaceHolder id="PH" runat="server" />
</ItemTemplate>
</asp:TemplateColumn>
</asp:datagrid>
I need to add a Button to the PlaceHolder depending on the values of the data I am binding. At the moment I am adding the Button after the data is bound in Page_Load. The problem is that the data binding methods are not called in postbacks, so the Button disappears when I click on it.
Problem is that I need to know some attributes of the grid item to create the Button, so I cannot create it before the data has been bound.

I have a Datagrid control in my webform, which directly pulls out data from our database.
For each row, I have a custom button at the last column. Its looks like:
[Code]....
What it does is it simply opens a new window with the row information.
The problem is, this button works with 2 clicks, not one click

I have a button, which when presses populates a grid with data. If I add an ObjectDataSource, and bind the grid to it, it will populate the grid when the page loads. But I need to populate the grid only if the button is pressed, because it is a lengthy operation.

I have a delete button in each row of GridView (component ASP.NET). I want some of the delete buttons to be invisible. The visibility of the delete button should depend on the data that are back the row.
GridView is backed by EntityDataSource. GridView displays entities called Category, one instance in each row. Entity Category has (besides others) also a field of type EntityCollection. Name of that field is Items. Basically I want to allow user to delete a row only if the Items field of backing Category entity is an empty collection.
This is how the button looks right now:
<asp:Button ID="DeleteButton" runat="server" CommandName="Delete"
Text="Delete"
Visible=??? ></asp:Button>
I don't know what should replace ???. The button schold be visible only when this expression evaluates to true:
((SimpleEShop.Model.Category) dataItem).Items.LongCount() <= 0
where dataItem variable contains data of current row in the table. What is the binding that I need ?
