Everthing works fine, i am able to export both the grids into a single excel.
but i had a question in this i have set page size as 100 as you can see so when i am exporting to excel only the 100 items are getting exported (which is right).
this is my code behind method for exporting

RadGrid radGrid = lbl_txt.Text == "All RadGrids" ? radGridWrapper : (RadGrid)radGridWrapper.Items[0].FindControl(lbl_txt.Text);

//html.Visible = false;

if (radGrid.Items.Count == 0)

{

Page.ClientScript.RegisterStartupScript(base.GetType(), "Alert", GC.Message("No records found"));

return;

}

if (isExcelExport = true)

{

gridcaption = "<b style='color: blue; text-align: left;'>Effort Analysis Report </b>";

if (CheckBox4.Checked == true)

{

gridcaption += "<BR/>" + "<b>Process : </b>" + ddlprocess.SelectedItem.Text + " " + "|" + " " + "<b>Group : </b> " + ddlGroupby.SelectedItem.Text + " " + "|" + " " + "<b>From Date :</b>" + txtFromDate.Text + " " + "|" + " " + "<b>To Date :</b>" + txtToDate.Text;

}

radGrid.MasterTableView.Caption = gridcaption;

radGrid.ExportSettings.FileName = "EffortAnalysis_" + "_from_" + txtFromDate.Text + "_to_" + txtToDate.Text;

radGrid.ExportSettings.OpenInNewWindow = true;

//radGrid.ExportSettings.IgnorePaging = true;

//radGrid.ExportSettings.ExportOnlyData = true;

gridBind();

radGrid.MasterTableView.ExportToExcel();

so if in this method i add in export settings as ignore paging i am getting an error saying the below message
Object reference not set to an instance of an object.

can any of you guys tell me how i can get over this speed bump

[Solved] Default Filter Error

If I put the following in the ASPX: <MasterTableView FilterExpression="([Active] = True)"> and put the CurrentFilterFunction="EqualTo" and CurrentFilterValue="True" on the GridBoundColumn Named Active The filter is set but does not filter the records.

If I put this in the codebehind on the NeedDataSource Method:

protected void rgManage_NeedDataSource(object source, Telerik.Web.UI.GridNeedDataSourceEventArgs e)

{

rgManage.DataSource = GetDataSet();

if (!Page.IsPostBack)

{

rgManage.MasterTableView.FilterExpression = "([Active] = True)";

GridColumn column = rgManage.MasterTableView.GetColumnSafe("Active");

column.CurrentFilterFunction = GridKnownFunction.EqualTo;

column.CurrentFilterValue = "True";

}

I get the following error on page load:

Expression expected

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: Telerik.Web.UI.ParseException: Expression expected

What am I missing here? Active is a boolean datatype.

VS2010 & Telerik.Web.UI_2010_2_713_Dev.msi

Hello, guys.
I've downloaded Telerik.Web.UI_2010_2_713_Dev.msi installation package and thought that now life will get much better.
Not a bit!
I uninstalled previos version of telerik ajax controls.
After installation I noticed the welcome message (something like "You hav just installed telerik...'). Toolbox looks ok.
But under Telerik menu I only can see "About" item and nothing more.
Any Telerik application templates have also disappeared.
Has anyone faced this?

With respect, Valery.
