    <p>It sounds to me like you want to use the ItemDataBound event.</p> <p><a href="http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.repeater.itemdatabound.aspx" rel="noreferrer">http://msdn.microsoft.com/en-us/library/system.web.ui.webcontrols.repeater.itemdatabound.aspx</a></p> <p>You will want to check the ItemType of the RepeaterItem so that you don't attempt to find the checkbox in Header/Footer/Seperator/Pager/Edit </p> <p>Your event would look something along the lines of:</p> <pre><code>void rptItems_ItemDataBound(object sender, RepeaterItemEventArgs e) { if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) { var checkBox = (CheckBox) e.Item.FindControl("ckbActive"); //Do something with your checkbox... checkBox.Checked = true; } } </code></pre> <p>This event can be raised by adding the event in your code behind like so:</p> <pre><code>rptItems.ItemDataBound += new RepeaterItemEventHandler(rptItems_ItemDataBound); </code></pre> <p>Or by adding it to the control on the client:</p> <pre><code>onitemdatabound="rptItems_ItemDataBound" </code></pre> <hr> <p>Alternatively you can do as the others suggested and iterate over the RepeaterItems, however you still need to check the itemtype.</p> <pre><code>foreach (RepeaterItem item in rptItems.Items) { if (item.ItemType == ListItemType.Item || item.ItemType == ListItemType.AlternatingItem) { var checkBox = (CheckBox)item.FindControl("ckbActive"); //Do something with your checkbox... checkBox.Checked = true; } } </code></pre> <p>You would want to do that in the <strong>Page PreRender</strong>, after the Repeater has been bound.</p>

    1. COYou just saved my rear man. I created this complex dynamically populated query with 2-3 nested repeaters with only one question left: how will the submit button report all the data? This solved everything. Thank you!

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
