How to change the content of a textbox programmatically

[Stephan]

Hi, Im sure it is possible, but I don t know how to do it. In designtime a added textboxes containing a label. In my webapplication I want to change the content of this label. When I debug I can see the textbox and its value. But how to reference the textbox in order to change its value.

Any help is appreciated.

Thx

In the Telerik help theres an example subscribing to the ItemDataBound event.  This would allow you to, Find/reference your textbox control and then replace its contents with something else:

using System.Data;
using Processing = Telerik.Reporting.Processing;

//...
private void detail_ItemDataBound(object sender, System.EventArgs e)
{
   // Get the detail section object from sender
   Processing.DetailSection section = (Processing.DetailSection)sender;
   // From the section object get the DataRowView
   DataRowView dataRowView = (DataRowView)section.DataItem;
   // Also from the section object get the items in the report
   Processing.ReportItemBase[] items =
           (Processing.ReportItemBase[])section.Items.Find("tbCombined", false);
   /// Get the specific report item you want to change,
   /// use the dataRowView to get the underlying data,
   /// then change the report item properties based on the data.
   if (items.Length > 0)
   {
       Processing.TextBox item = items[0] as Processing.TextBox;
       item.Value =
           dataRowView["FirstName"].ToString()
           + " " +
           dataRowView["LastName"].ToString();
   }
}

Hi Jafin,

that was what I was looking for. At first I thought is was possible on the page where the report is shown (rendered), but I see I have to do it in the report itselft.

Thanks for the help.

Hello Stephan,

This is possible through the calling application as well. Here is a sample:

   protected void Button1_Click(object sender, EventArgs e)
        {
            Telerik.Reporting.TextBox txt = this.ReportViewer1.Report.Items.Find("textBox1", true)[0] as Telerik.Reporting.TextBox;
            txt.Value = "set through app";
        }

Hope this helps.

Sincerely yours,

Hello

it looks like the last proposed solution

    Dim txt As Telerik.Reporting.TextBox = TryCast(Me.ReportViewer1.Report.Items.Find("textBox1", True)(0), Telerik.Reporting.TextBox)
    txt.Value = "set through app"

is now obsolete and I could not find the replacement syntax ...

Thanks for providing the new syntax

Hello Pierre-Jean,

You can take a look at Access Report Items Programmatically which provides different approaches in C#/VB for accessing a report item from within the report and from the invoking application. 

Let us know if you need further help.
