Post is about the bug I found when we do inline editing in GridView control of ASP.Net in web application.
To understand this fully follwing is my gridview code in AspX file
Code in .Aspx.cs File
As you see in code I have written code RowDataBound which find textbox control and attach javascript with it. And second thing to notedown is that it finds textbox and attach script with it when row is in edit mode. This code works fine its attach script wwith the textbox when row is in edit mode.
Problem
But this code dont work when I click on edit butoon of alternet row which means that it not satisfy if condition. In Edit mode alternet row sate is "Alternet | Edit" where as when you click edit of non-alternetrow rostate is "Edit" which statify the if condition.
You weill get edit by below image where in immediate window it shows sate of alternet row.
Solution
Following is solution to avoid problem with the alternet row edit.
To understand this fully follwing is my gridview code in AspX file
As you see in code I have attahced RowDataBound which fires when data get bound with the each row of the grid and RowEditing which get fire when user press edit button of the row in gridview.
Code in .Aspx.cs File
#region Grid Events
protected void grdView_RowEditing(object sender, GridViewEditEventArgs e)
{
grdFXRate.EditIndex = e.NewEditIndex;
BindGrid();
}
protected void grdView_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
grdView.EditIndex = -1;
BindGrid();
}
protected void grdView_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
//get data and update
int Currency_Rate = 0;
TextBox txtRate = row.FindControl("txtRate") as TextBox;
if (txtRate != null)
Currency_Rate = Convert.ToDouble(txtRate.Text);
saveDetails();
grdView.EditIndex = -1;
BindGrid();
}
protected void grdView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowState == DataControlRowState.Edit )
{
GridViewRow row = e.Row;
TextBox txtRate = row.FindControl("txtRate") as TextBox;
if (txtRate != null)
txtRate.Attributes.Add("onKeypress", "IntegerAndDecimal(event,'" + txtRate.ClientID + "',true)");
}
}
#endregion Grid Events

protected void grdView_RowDataBound(object sender, GridViewRowEventArgs e)
{
if ((e.Row.RowState & DataControlRowState.Edit) > 0)
{
GridViewRow row = e.Row;
TextBox txtRate = row.FindControl("txtRate") as TextBox;
if (txtRate != null)
txtRate.Attributes.Add(
"onKeypress", "IntegerAndDecimal(event,'" + txtRate.ClientID + "',true)");
}
}
As you see in code condtion e.Row.RowState & DataControlRowState.Edit satisfy the for both alternet and non-alternet row and works fine.
