Accepted answer
In the DataBound event, add javascript to the textbox or add validation controls like requiredfield validator controls etc...

Here is the snippet.

RequiredFieldValidator RequiredFieldValidator1 = new RequiredFieldValidator();
RequiredFieldValidator1.Enabled = true;
RequiredFieldValidator1.ErrorMessage = "First field required";
RequiredFieldValidator1.Display = ValidatorDisplay.Dynamic;
RequiredFieldValidator1.ControlToValidate = txtName.Id;
this.page.Controls.Add(RequiredFieldValidator1);
RequiredFieldValidator1.Validate();

No, I havn't given any default value for that text box.
I am writing something in that text box, after clicking button, I am not getting that value.

Can you please confirm the following?
Have you trimmed the value in the databound event before adding it to the controls collection?
Do you have any default text for the textbox control?
shibasankar behera13y ago
yes Sir,
still I am getting that

It means after the databind, correct?.
You meant to say, still you're getting &nbsp in the javascript and gridview ?

When do it in the rowdatabound event, you should get the values in the gridview.
So, I'm unclear here. Can you please explain bit more?

Just trim the textbox value before adding it to the controls collection.

protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
try
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
for (int colIndex = 2; colIndex < e.Row.Cells.Count; colIndex++)
{
TextBox txtName = new TextBox();
txtFName.Text = e.Row.Cells[colIndex].ToString();
txtFName.Text = txtFName.Text.Trim();
e.Row.Cells[colIndex].Controls.Add(txtName);
}
}
}
catch(Exception ex)
{
Response.Write(ex);
}
}
