Hello experts, here is what i want to accomplish. I have a lable displaying Department name in the itemtemplate of gridview. When i click Edit linkbutton(inside the Itemtemplate) the edittemplate for the department which is a dropdownlist will be shown. But after i populate this dropdownlist i can't get it to select the value that was initially in that field. I have written the following code in the rowcommand event handler...

C#

else if (e.CommandName.ToLower().Equals("edit"))
            {
                GridViewRow grdRow = (GridViewRow)(((LinkButton)e.CommandSource).NamingContainer);
                //int nIndex = grdRow.RowIndex;
                strDeptSelectedValue = grdRow.Cells[3].Text;
                strPositionSelectedValue = grdRow.Cells[4].Text;
            }

i want to get the Cell content of the row and store it in a static string...and i want to be able to utilize this string in the RowEditing Eventhandler as follows...

C#

DropDownList drpDlistEditDept = (DropDownList)grdQuestionGroup.Rows[e.NewEditIndex].FindControl("drpdlistEditDept");
            DropDownList drpDlistEditPosition = (DropDownList)grdQuestionGroup.Rows[e.NewEditIndex].FindControl("drpDlistEditPosition");

            ds = DepartmentDA.SelectAll();
            drpDlistEditDept.DataSource = ds.Tables[0];
            drpDlistEditDept.DataTextField = "Name";
            drpDlistEditDept.DataValueField = "Code";
            drpDlistEditDept.SelectedValue=//The static string here.
            drpDlistEditDept.DataBind();

however the static string always comes out to be a "" string. Why is the Cell[3].Text and Cell[4].Text not giving any value?? I have debugged and checked...the grdRow is getting the value as it should...

drpDlistEditDept.DataBind();
drpDlistEditDept.SelectedValue=//The static string here.

Try these changes now,

Firstly, get your Gridview in RowCommand event like this

C#

protected void gvProduct_RowCommand(Object sender, GridViewCommandEventArgs e)
   {
       if (e.CommandName == "AddNewRow")
       {
           GridView gvProduct = (GridView)sender;

       }
   }

If you still don't get cell values, then try following changes too. You will definitely get your required values.

Use Labels by find Control for getting values in GridView RowCommand Event.

C#

Label lblValue1 = (Label)gvData.Rows[rowIndex].FindControl("lblValue1");
Label lblValue2 = (Label)gvData.Rows[rowIndex].FindControl("lblValue2");
strDeptSelectedValue = lblValue1.Text;
strPositionSelectedValue = lblValue2.Text;
