Gridview Control Edit Mode requires Pressing Edit Button Twice

Hi all..

I have a GridView control in an ASP.NET 2.0 page. I added a column that
contains edit, update, cancel buttons. Because I did that, I had to handle
RowEditing event or an exception was thrown.

Well... this is the body of the RowEditing event:

protected void gvParametros_RowEditing(object sender, GridViewEditEventArgs
e)
{
gvParametros.EditIndex = e.NewEditIndex;
}

The fact is that when page is loaded and I click the edit link, page is
refreshed but GridView doesn't enter edit mode. When I press edit link
again, GridView enters edit mode.

any help to solve this behavior would be greatly appreciated

rebind the datagrid

protected void gvParametros_RowEditing(object sender, GridViewEditEventArgs
e)
{
gvParametros.DataBind()
gvParametros.EditIndex = e.NewEditIndex;
}

Yes, you'd think that that is how it would work (rebinding).I am a total newbie at C#/ASP.Net BTW so be gentle with me.

I tried as you suggested and it calls "Page_PreRender" and the Gridview disappears from the screen when it exits the Page_PreRender Event. The Page.IsPostBack property is true.

protected void Page_PreRender(object sender, EventArgs e)
{
if (!Page.IsPostBack)
{
BindData();
}
}

// Editing mode
protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.DataBind();
GridView1.EditIndex = e.NewEditIndex;
}

private void BindData()
{
GridView1.DataSource = dataExp;

GridView1.DataMember = "EXPENSE";
GridView1.DataBind();
}

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
BindData();

}

I changed the sequeence as suggested to:

protected void GridView1_RowEditing(object sender, GridViewEditEventArgs e)
{
GridView1.EditIndex = e.NewEditIndex;
BindData();

}

No change in result (i.e. Grid still dissapeared)

Thanks for that. The dataexp was being cleared so obviously things were a bit of a mess. I took a deep breath scrapped the entire class and rewrote the code and it worked first time. Thanks Again
