Hi there,
i have a textbox in the groupHeaderSection1 called ResourceDivision. I am trying to test out the callbacks on the sections to see how to manipulate the data in the textbox.
The datafield property of the textbox is set up to pull text from the datasource, and it is displaying the text from the datarecord properly.
However..
1) I'd expect ResourceDivision.text content to be the dynamic content from the data record when stopping at breakpoints in the debugger in all callbacks. At least in one of the callbacks listed below? It isnt: it is showing the default text that's defined in the property panel for the textbox.
Looks like the data actually only gets bound to the textboxes AFTER the callbacks are triggered? Help?
2) I'd expected to be able to modify the data in the textbox through the callbacks, but since it seems to the actual binding is happening AFTER the callbacks it is actually overwritten with the actual datarecord's content.
private void groupHeaderSection1_ItemDataBinding(object sender, EventArgs e)
{
this.ResourceDivision.Text += "-1";
//this is nor reflected anywhere?
}
private void groupHeaderSection1_ItemDataBound(object sender, EventArgs e)
{
this.ResourceDivision.Text += "-2";
//this is nor reflected anywhere?
}
private void detail_ItemDataBinding(object sender, EventArgs e)
{
this.ResourceDivision.Text += "-3";
//this is nor reflected anywhere?
}
private void detail_ItemDataBound(object sender, EventArgs e)
{
this.ResourceDivision.Text += "-4";
//this is nor reflected anywhere?
}
Thanks,
Eric

I was talking nonsense. The API is just slightly different than I anticipated:
You can bind per section or per data element (i.e. textbox).
so if you specify the ItemDataBound callback per textbox you can modify
the text pulled from the datasource to anything there.
All good!

private void txtManufacturer_ItemDataBound(object sender, EventArgs e)
{
Telerik.Reporting.TextBox tb = (Telerik.Reporting.TextBox)sender;
tb.Text += "-1";

I noticed in the itembound you are passed a reference to the textbox itself through the 'Object sender' parameter. But how can you maipulate other textboxes in that callback? (Just accessing it by the Id specified in the design view doesnt work which is understood as there can be multiple instances of the textbox: one for each record.)
Also: page numbering? I dont see where I can specify those?
Thanks!
In this first CTP version of telerik Reporting events are only added to demonstrate that there will be such. This is by no means their final and working version. We are currently working on the events mechanism and it will surely evolve with the next pre-beta versions.
Thank you for your suggestions, this was some very helpful insight and we will definitely have it in mind while developing our reporting tool.
Best wishes,
