How to Delete Repeater Row using button click?

Raja

I have add the empty row for repeater using below code

protected void btnAddRow_Click(object sender, EventArgs e)
{
DataTable dt = new DataTable();
dt = AddDataTable();
if (dt.Rows.Count >= 1)
{
dt.Rows.Add();
rptrReference.DataSource = dt;
rptrReference.DataBind();
}
btnSave.Focus();
}

protected DataTable AddDataTable()
{
DataTable dtReference = new DataTable("Project");
dtReference.Columns.Add("IN_ORGAN_CODE");
dtReference.Columns.Add("IN_COMP_REF_NO");
dtReference.Columns.Add("IN_REFERENCE_TYPE");
int rowID = 0;
dtle = dtReference.Clone();
TextBox tbxCode = new TextBox();
foreach (RepeaterItem dataItem in rptrReference.Items)
{
tbxCode = (TextBox)dataItem.FindControl("tbxCode");
dtle.Rows.Add();
dtle.Rows[rowID]["IN_ORGAN_CODE"] = 9212;
dtle.Rows[rowID]["IN_COMP_REF_NO"] = tbxLegacyCode.Text.Trim().ToUpper();
dtle.Rows[rowID]["IN_REFERENCE_TYPE"] = "PRF";
rowID++;
}
return dtle;
}

"no if user add five rows and last min he not want 3 row then how to delte it"

First get value which rows are selected based on checkoxes. Find below:
foreach( RepeaterItem aItem in rptrReference.Items){
   HtmlInputCheckBox chkDisplayTitle = (HtmlInputCheckBox)item.FindControl("chkDisplayTitle");
   if(chkDisplayTitle.Checked) {
      //HERE IS YOUR VALUE: chkAddressSelected.Value
   }
}
Based on checkbox value either add or delete to datatable like below:
// Delete the record whose ID is 1. playerTables is DataTable object
playerTables.Select("ID == 1").Delete();

You are heading correct way. Because you are looping all items in row and getting value. Here you can apply your logic if it is needed to add in repeater. If it satisfies your condition then add the to datatable otherwise not.
