SubReport ItemDataBound

[Fredrick Smith]

Hello,

I have a pretty basic question.

I have a SubReport. I want to access items when they are being "DataBound", so I wired the SubReport's ItemDataBound inside the document I use as the SubReport (and not inside the main report's SubReport item).

Is this the correct way to do it?

Thanks,

Ricardo

Hello Ricardo,

Attached you may find a sample that demonstrates one of the possible ways to access the subreport's data from the master (outside) report.

For the purpose of the example I'm using a simple data tables filled in by hand.

The idea is as follows: the detail section of the nested report - DetailReport - was exposed (making in public) and inside the MasterReport I've handled the DetailReport detail section's ItemDataBound event.

Ok, I tried the demo, but the problem is, I'm not getting any value in the textbox at the botom, it just says textBox3. And I had to change the line from

textBox3.Text = string.Format("Total Sum of detail IDs: {0}", this.totalSum);

 to

textBox3.Value = string.Format("Total Sum of detail IDs: {0}", this.totalSum);

so that it would compile. Any ideas on what is not working?

Thanks!

Hi Ricardo,

It seems that you're still working with the pre-SP1 version, where the Telerik.Reporting.Processing.TextBox.Text property was read-only. In SP1 (aka Telerik Reporting v1.1) we made it read-write.

Please follow the instructions of this KB article to update to the latest Telerik Reporting version.

Thanks for the help. It is almost done right now.

My last problem is this:

In each subreport(details record), what I do is the following:

1. Read values from the DataItem of the current row.
2. Evaluate the read integer and use its bit value to set variables
3. Output the value of the set variables to the fields on the details report.
   

The problem I'm facing now is that the information is being shown one record behind. For example, the details that correspond to the first record are being displayed on the second record's fields and so on. This only happens on the fields I'm setting using the detail_ItemDataBound Event function.

 I made a printout of all the reports and my data in the DataBase and I can confirm they are being displayed one record behind.

Any ideas?

Thanks for all the help. I'm almost done!!

I found a solution.

Instead of using detail_ItemDataBound event of the details part on the SubReport, I used the detail_ItemDataBinding event and this solved my problems.

Thanks for all the help!
