Change text at runtime?

[Will]

Hello (again) -

On my report's page header, I have a text box and when the report is generated, the text value needs to change depending on the item from a drop-down list on the web page.

I have tried a few ways to get this to work but I have not been succesful.  Does anyone know of a way to do this with the report control on a web page?  I can save the drop-down list selected value as a Session variable if necessary.

Thanks

Hi Will,

You can add a public property to your report that will expose the value of the TextBox so that it can be set from outside. For example, if the TextBox is called textBox1:

public class MyReport : Report
{
         //Code omitted
        public string MyDynamicValue
        {
            set
            {
                this.textBox1.Value = value;
            }
        }
         //Code omitted
}

Then after you create your report and before you show it, you can set this property depending on your session variable:

protected void Page_Load(object sender, EventArgs e)
{
    Report report = new MyReport();
    report.MyDynamicValue = mySessionVariable;
    this.ReportViewer1.Report = report;
}

Hope this helps.

This will solve my problem.  I cannot believe I forgot how the other report parameters (for the stored proc) were created and exposed to the calling page. 

Thanks as always for the great help.

Hi Will,

I have attached a sample solution that covers the case you are asking for. This solution contains three projects:

1. WebSite - this web site project keeps track of selected comboBox items and reloads the report. The report was reinitialized according to the selection of comboBox (see Default.aspx.cs file for code implementation);
   
2. Report1 - this class library project contains a specific report. This report has a ReportType property which you could use to change the textBox item in report's header and to change report's DataSource too (see ReportType property and ReportCS1_NeedDataSource method in Report1CS.cs file);
    
3. Windows app - this complementary project shows how to deal with this case in a windows forms app.

To build this solution you should fix the references to the Telerik reporting assemblies according to your configuration.
