Forms Data Controls :: GridView:Dynamic DataBound Column Creation With Hyperlinks?
May 10, 2010I have a stored procedure (For Eg: sp_GetAvlData) that accepts a number of parameters, 3 of which are TimeFrom, TimeTo (as varchar) and TimeInterval (as int), formulates a Dynamic query and executes itself. So for instance, if I call the proc as follows:
[code]....
dtAvl is the datatable containing the results of my stored procedure.
The next step for me is to make each of the cells (except the cells in the first column) as a Hyperlink so that when clicked upon a cell, it populates 2 textboxes with the selected Timeslot and Name or ID (ID field is not displayed in Gridview). The textboxes are located on the same page but outside of the Gridview control.
The Challenge that I'm facing out here are:
1) As you can see, the field names being generated are not fixed and I have no control over them.
2) Because the field names are not fixed I'm not sure I can implement this using the Templatefields or BoundFields of Gridview.
Is there any way to achieve the Hyperlinking of these cells within the Gridview?

Column In DataView Not Rendering When Databound To DataGrid (or RadGrid)?
Sep 7, 2010Using ASP.NET Web Forms.I am databinding a DataView to a DataGrid with AutoGenerateColumns set to trueThe final column of the DataView is not rendering.Using the debugger I can see that the column definitely exists in the data grid's datasource. The column is of type decimal and some of the rows in the column have data in them.The column has a column name.The other columns are rendering fine.What's going on?Some more infoFunnily enough, I can set AutoGenerateColumns to false, then just add the columns manually:
datagrid.Columns.Clear();
foreach(DataColumn column in dataView.Table.Columns)
{
datagrid.Columns.Add(new BoundColumn {
HeaderText = column.ColumnName });
}
datagrid.DataSource = dataView;
This works fine. Why can't .NET do this with AutoGenerateColumns?

C# - Which Databound Control Should Be Use For Nested Databound Controls?
Dec 7, 2010I want to render something like this (with ASP.Net Controls in the codebehind):
<ul>
<li class="first"><h1>This is a caption</h1></li>
<li><a href="#" title="" target="_self">Foo</a></li>
<li><a href="#" title="" target="_self">Foo1</a></li>
<li><a href="#" title="" target="_self">Foo2</a></li>
<li><a href="#" title="" target="_self">Foo3</a></li>
<li><a href="#" title="" target="_self">Foo4</a></li>
</ul>
<ul>
<li class="first"><h1>This is a another caption</h1></li>
<li><a href="#" title="" target="_self">Foo5</a></li>
<li><a href="#" title="" target="_self">Foo6</a></li>
<li><a href="#" title="" target="_self">Foo7</a></li>
<li><a href="#" title="" target="_self">Foo8</a></li>
<li><a href="#" title="" target="_self">Foo9</a></li>
<li><a href="#" title="" target="_self">Foo10</a></li>
<li><a href="#" title="" target="_self">Foo11</a></li>
</ul>
The amount of li elements that will be rendered into each ul is determined at runtime. Each link in a li belongs to into a specific ul (the one containing a specific caption. Imagine this as a kind of a treeview with nodes and subnodes) During the bind Event I need access to an ASP:HyperLink that will be rendered into the a-element. Which databound ASP.Net control should I pick for this? Looks like a repeater in a repeater, which should make the databinding process ugly. I'm thinking about creating this HTML-Output with StringWriters myself.
Forms Data Controls :: Sorting A Column By Simply Clicking On The Column Rather Than Clicking On The Column Header?
Jan 14, 2010I am looking to sort a column on my gridview by simply clicking on the column rather than clicking on the column header.

View 2 RepliesWeb Forms :: Execute Javascript On DataBound?
Jul 19, 2010I have a content page that displays search criteria in a div. I would like to hide the criteria div when results are returned, but keep it visible if no results are found. I have code in the DataBound event for the gridview that displays the number of rows returned from the query which works fine. To show the search criteria, I have a RegisterStartupScript which calls the javascript function to show the div. Even though the RegisterStartupScript code is executed, the javascript never runs (I put an alert in the function that never fired). Is this a lifecycle timing issue? I just don't see how I can register the javascript earlier in the page lifecycle if it is. I would think this is a very common requirement.

View 4 RepliesWeb Forms :: Databound Happens Earlier Than Buttonclick?
Dec 30, 2010I have trouble with the sequence of events on my page. I have a button, which on its onClick event calls a method, which posts data to a database, and causes a postback. But on the same page I have a repeater which uses the data that is being modified by the button. I would need somehow the buttonclick event occur "earlier" than the databinding in the repeater to show the correct data.

Nov 11, 2010I am fairly new to asp.net programming. I found this custom control that uses ajax to update the contents of the control and it is working perfectly.

Web Forms :: Formview Same Id For Controls Allowed Only If Databound?
Apr 5, 2010I've got a formview with controls in different template views and I have a query just out of curiosity.
In my edit template I've got for example:
<asp:TextBox ID="IsPrestigeTextBox" runat="server" Text='<%# Bind("IsPrestige") %>' />
<asp:CheckBox ID="IsPrestigeChkbx" runat="server" />
and then the same code exactly in my insert template:
<asp:TextBox ID="IsPrestigeTextBox" runat="server" Text='<%# Bind("IsPrestige") %>' />
<asp:CheckBox ID="IsPrestigeChkbx" runat="server" />
However, the databound items seem to be allowed to have the same ID whereas the non-databound checkboxes arent.
What's going on there?
