adding rows dynamically to a gridview problem


W

WebBuilder451

I'm adding subheadings to a gridview. Each sub head has a few link buttons.
I'm adding the controls in the rowdatabound event code follows: sorry about
the length here. I have to be missing something. The buttons show up and post
back, but the events do not fire.
any help would be appreciated!!!

Thank you.

You don't need to add controls dynamically. Instead, use templated fields
made out of 2 rows, one for regular items and another for those with
subheadings. In the RowDataBound event decide if you need to show
subheadings.

If you can, it is better to use a ListView control since it allows using one
item template for the whole row, like in a repeater, as opposed to per-field
templates in GridView.

Here is an example for a repeater. It will help you to get the idea:

<asp:repeater>
<headertemplate>
<table>
</headertemplate>
<itemtemplate>
<tr runat="server" id="trNormal">
<td>Databind expression for column 1</td>
<td>Databind expression for column 2</td>
<td>Databind expression for column 3</td>
</tr>
<tr runat="server" id="trSubheadings">
<td>Databind expression for subheading 1</td>
<td>Databind expression for subheading 2</td>
<td>Databind expression for subheading 3</td>
</tr>
</itemtemplate>
</asp:repeater>
<footertemplate>
</table>
</footertemplate>

Handle ItemDataBound event to hide trNormal or trSubheadings as needed.

ok, thanks
This was a bit more straight forward than i expected. I thought you ment to
create a custom template type for the subhead. perhaps using template builder.
thanks very much appreciated.

You don't need to add controls dynamically. Instead, use templated fields
made out of 2 rows, one for regular items and another for those with
subheadings. In the RowDataBound event decide if you need to show
subheadings.

If you can, it is better to use a ListView control since it allows using
one
item template for the whole row, like in a repeater, as opposed to
per-field
templates in GridView.

Please help

ok, thanks
This was a bit more straight forward than i expected. I thought you ment to
create a custom template type for the subhead. perhaps using template builder.
thanks very much appreciated.

Here is an example for a repeater. It will help you to get the idea:

<asp:repeater>
<headertemplate>
<table>
</headertemplate>
<itemtemplate>
<tr runat="server" id="trNormal">
<td>Databind expression for column 1</td>
<td>Databind expression for column 2</td>
<td>Databind expression for column 3</td>
</tr>
<tr runat="server" id="trSubheadings">
<td>Databind expression for subheading 1</td>
<td>Databind expression for subheading 2</td>
<td>Databind expression for subheading 3</td>
</tr>
</itemtemplate>
</asp:repeater>
<footertemplate>
</table>
</footertemplate>
