I am exporting the grid to excel using an image button click event as follows:

protected void ImageButton1_Click(object sender, System.Web.UI.ImageClickEventArgs e)

{

string fileName = "";

List<ProjectBO> listProjectBO = ProjectDAP.GetAllProjects();

if (listProjectBO.Count > 0)

{

// Exported excel file name contains of ClientName,ProjectName,ArrivalDate

fileName = "ProjectData";

}

radGridProject.DataSource = ProjectDAP.GetAllProjects();

radGridProject.Rebind();

//radGridProject.AutoGenerateColumns = true;

radGridProject.ExportSettings.FileName = fileName;

radGridProject.MasterTableView.Columns.FindByUniqueName("ProjectIDColumn").Visible = true;

radGridProject.MasterTableView.ExpandCollapseColumn.Visible = false;

radGridProject.MasterTableView.RowIndicatorColumn.Visible = false;

radGridProject.MasterTableView.Columns.FindByUniqueName("ProjectsEditButton").Visible = false;

radGridProject.MasterTableView.Columns.FindByUniqueName("ProjectsDeleteButton").Visible = false;

radGridProject.MasterTableView.Columns.FindByUniqueName("MSTProjectIDColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("ProjectTypeColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("ProjectDescriptionColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("ClientIDColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("ClientNameColumn").Visible = false;

radGridProject.MasterTableView.Columns.FindByUniqueName("StNumberColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("StPreColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("StNameColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("StTypeColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("StSuffixColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("LatMinColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("LatMaxColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("LongMinColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("LongMaxColumn").Visible = true;

radGridProject.MasterTableView.Columns.FindByUniqueName("ProjectNotesColumn").Visible = true;

this.radGridProject.GridLines = GridLines.Both;

radGridProject.ExportSettings.Excel.Format = GridExcelExportFormat.Html;

this.radGridProject.ExportSettings.ExportOnlyData = true;

this.radGridProject.ExportSettings.IgnorePaging = true;

foreach (GridItem commandItem in this.radGridProject.MasterTableView.GetItems(GridItemType.CommandItem))

{

commandItem.Visible = false;

}

radGridProject.MasterTableView.ExportToExcel();

}

Problem is that when ever I export and open the excel sheet an empty column "A" is shown in the excel sheet and then the columns specified as shown in further column in sheet. I need to remove this column "A". Is it so that while exporting to excel the columns starts from "B" in excel sheet and not "A"..?

Please help me I need to remove this column "A " from excel sheet or rather it should not get displayed at all.

Thanks.

Hi Prajakta,

I suppose you want to hide the Expand/Collapse column in the exported file. If so try to add the following code before exporting and see if it helps:

protected void Export_Click(object sender, EventArgs e)

{

RadGrid1.ExportSettings.OpenInNewWindow = true;

foreach (GridDataItem item in RadGrid1.Items)

{

item["ExpandColumn"].Visible = false;

}

RadGrid1.MasterTableView.ExportToExcel();

}
