Hi,

I have a dropdownlist which is binded with database programatically. I need to show programatically the desired item which is already in the control.

In my project, I have an entry form in that I've a DropDownList which binds with db through code. In another form have Gridview while clicking edit, in popup window the same control is there. But I have to show the already inserted value in that control.

Please help me to do so.

C#

DataRowView drview = (DataRowView)e.Row.DataItem;
        if ((e.Row.RowState & DataControlRowState.Edit) > 0)
        {
            DropDownList ddExp = (DropDownList)e.Row.FindControl("ddExp");
            if (ddExp != null)
            {
                ddExp.Text = drview["Expense_Type"].ToString();
            }
        }

use the above code in rowdatabound where ddExp is your dropdown

this is not my requirement.

While clicking the grid, get the id and pass the id to a popup window. On that window I get the values from db according to the id and assign the values to the controls which are in that window. Previously mentioned dropdownlist is in this window. Here I have to show the value corresponding to the value I already inserted.

Hope that you understood my problem. Kindly help me to do.

Solution 2

what is your actual problem. may be you are not getting the querystring

for that use

C#

string qrystring=Request.querystring["db_column"].tostring();

and now bind dropdown and other control via this qrystring.

try

C#

string somevariable=dr["dbcolumn"].toString(); //if you are using datareader

 string somevariable=dt.rows[0]["dbcolumn"].tostring(); //if you are using datatable

 dropdown.selecteditem.text=somevariable;  //in this case somevariable should be there in dropdownlist.
