    <p>I searched SO, google &amp; Telerik forums, but could not find a solution. </p> <p>I have an existing app (written by a previous developer) that is calling a stored procedure that populates a RadGrid control. It populates fine the first time around. </p> <p>However, when I change the date parameter, click "search" button, I get a blank RadGrid control. When I click search the second time, the grid is populated. When I walk through the code, I get an error message </p> <blockquote> <p>Column 'ID' does not belong to table Table.</p> </blockquote> <p>How can I resolve the issue of having to click search twice to display data ? </p> <p>My code behind is: </p> <pre><code>protected void btnSubmit_OnClick(object sender, EventArgs e) { try { ViewState["newset"] = null; CreateDatasource(); this.RadGrid1.DataBind(); this.RadGrid1.CurrentPageIndex = 0; ViewState["newset"] = "new"; string idex = this.hdnindex.Value; if (idex != string.Empty) this.RadGrid1.MasterTableView.Items[int.Parse(idex)].Selected = true; } catch (Exception ex) { this.lblMessage.Text = ex.Message; } } protected void RadGrid1_ItemCreated(object sender, GridItemEventArgs e) { try { if (e.Item is GridDataItem) { GridDataItem item = (GridDataItem)e.Item; HyperLink hLink = (HyperLink)item["ViewHyperLink"].Controls[0]; if (hLink != null) hLink.Attributes.Add("onclick", "selectMe('" + item.ItemIndex + "');"); } } catch (Exception ex) { this.lblMessage.Text = ex.Message; } } </code></pre> <p>In the code behind above, when this.RadGrid1.DataBind() is called, the code steps into <code>RadGrid1_ItemCreated</code> loops through the if statement a few times, them goes into the if statement, comes out of the function, and then the catch statement of btnSubmit is called, which displays the error message "Column ID does not belong to table Table". </p> <p>Any ideas on how to resolve this?</p>

    1. COWith an exception message like that, it sounds like there's a binding problem between the RadGrid and the data source.

    2. COThanks for your response. Can you expand on that (or have any suggestions) ? I have tried pretty much every which way of binding I can think of.

    3. COCan you include your stored procedure and the logic that is populating the RadGrid?

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.
