I want to fill gridview textbox by selecting data from gridview Dropdownlist

[raju melveetilpurayil]

try like this

//DropDownList inside the gridview
protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e)
{
//identifying DropDownList
DropDownList gridDropDownList = (DropDownList)sender;
//selecting grid row
GridViewRow gridRow = (GridViewRow)gridDropDownList.NamingContainer;
//setting Index
int selectedIndex = gridRow.DataItemIndex;
//finding textbox in selected gridview row
TextBox textBox = (TextBox)GridView1.Rows[selectedIndex].FindControl("yourTextBoxID");
string selected = gridDropDownList.SelectedValue;
if (textBox != null)
{
textBox.Text = selected;
}
}

Hi, I suggest to you a javascript client solution: add this javascript function somewhere in your project

function selectChoice(ddl, textboxID) {
var chosenoption = ddl.options[ddl.selectedIndex];
if (chosenoption.value != 'nothing') {
document.getElementById(textboxID).value = chosenoption.value;
}
}

add onrowdatabound event for your grid with this code:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
DropDownList ddlChoice = e.Row.FindControl("ddlChoice") as DropDownList;
TextBox txtSelectedValue = e.Row.FindControl("txtSelectedValue") as TextBox;

    string jScript = "selectChoice(this, '{0}');";
    ddlChoice.Attributes.Add("onchange", string.Format(jScript, txtSelectedValue.ClientID));
}

}
