I am having two dropdownlists that are interrelated, in which one is vertical ddl and the other department ddl in a grid view
if we select the vertical ddl then corresponding departments have to appear in department ddl.
I've written the code like this
In footer of gridview i successful managed to embed the two dropdowns,
But when edit mode i am not able to identify the row index
Note: i am using onselected index changed event in vertical ddl in both footer and edit mode,
but i am not able to get the row index of gridview.
here is example code for footer:
protected void Onverticalselection(object sender,EventArgs e) //onselectedindexchanged event of vertical ddl
{
objBW= new BWizard_demomast();
dsmdemo=new DataSet();//ekkada datatable kudha use cheyachu
string Flag;
Vertical = string.Empty;
Department = string.Empty;
DropDownList ddlvert = new DropDownList();
ddlvert = (DropDownList)gdviw1.FooterRow.FindControl("ddlvertF");
DropDownList ddldepart = new DropDownList();
ddldepart = (DropDownList)gdviw1.FooterRow.FindControl("ddldepartF");
Flag = ((DropDownList)gdviw1.FooterRow.FindControl("ddlvertF")).SelectedValue;
dsmdemo = objBW.GetdropdownsBW(Flag,Vertical,Department);
ddldepart.Items.Clear(); //previous selected items ni eliminate cheyadaniki
if (dsmdemo.Tables.Count > 0)//ekkada datatable use cheste tables[0].rows.count ani vadali
{
if (dsmdemo.Tables[0].Rows.Count > 0)
{
ddldepart.DataSource = dsmdemo.Tables[0];
ddldepart.DataValueField = dsmdemo.Tables[0].Columns["LOCATION_VALUE"].ColumnName;
ddldepart.DataTextField = dsmdemo.Tables[0].Columns["LOCATION_CODE"].ColumnName;
ddldepart.DataBind();
}
}
ddldepart.Items.Insert(0, new ListItem("Select", ""));
}how can we identify the control in the edit mode.
please do needful at the earliest, i am working on a project
