Grid view row updating does not get new entered values

Dec 20, 2012 03:01 AM|LINK

I have used below code for grid view row updating, but after click on update button, it takes old values.

I checked by break point for grid view row updating , all the text boxes have old values. And new entered values do not grab.

I tried a lot in goggle but I could not solve the problem.

protected void GridViewDocuments_Search_RowUpdating(object sender, GridViewUpdateEventArgs e)
    {


            _DataContext = new EDMSDataContext();

            int _Docid = (int)GridViewDocuments_Search.DataKeys[e.RowIndex].Value;

            TextBox DocumentNo = (TextBox)GridViewDocuments_Search.Rows[e.RowIndex].FindControl("DocumentNo");

            TextBox title = (TextBox)GridViewDocuments_Search.Rows[e.RowIndex].FindControl("title");
            TextBox unit = (TextBox)GridViewDocuments_Search.Rows[e.RowIndex].FindControl("unit");

            TextBox originator = (TextBox)GridViewDocuments_Search.Rows[e.RowIndex].FindControl("originator");

            _DataContext.updateDoc(_Docid, DocumentNo.Text, title.Text, unit.Text, originator.Text);
            _DataContext.SubmitChanges();
            GridViewDocuments_Search.EditIndex = -1;
    
       
            var query = _DataContext.spQuickSearchDoc(txtSearchKeywords.Text);

             GridViewDocuments_Search.DataSource = query;
            GridViewDocuments_Search.DataBind();

        }

protected void GridViewDocuments_Search_RowEditing(object sender, GridViewEditEventArgs e)
    {
        //var query = _DataContext.spQuickSearchDoc(txtSearchKeywords.Text);
       // GridViewDocuments_Search.DataSource = query;
        GridViewDocuments_Search.EditIndex = e.NewEditIndex;
        GridViewDocuments_Search.DataBind();
    }

protected void btnSearch_Click(object sender, EventArgs e)
    {
        
            _DataContext = new EDMSDataContext();
            var query = _DataContext.spQuickSearchDoc(txtSearchKeywords.Text);
            GridViewDocuments.Visible = false;
            GridViewDocuments_Search.Visible = true;
            GridViewDocuments_Search.DataSource = query;
            GridViewDocuments_Search.DataBind();

        
    }

Grid view marks up:

              Visible="False" onrowcommand="GridViewDocuments_Search_RowCommand" OnRowDeleting="GridViewDocuments_Search_RowDeleting"

protected void GridViewDocuments_Search_RowEditing(object sender, GridViewEditEventArgs e)
    {
        //var query = _DataContext.spQuickSearchDoc(txtSearchKeywords.Text);
       // GridViewDocuments_Search.DataSource = query;
        GridViewDocuments_Search.EditIndex = e.NewEditIndex;
        GridViewDocuments_Search.DataBind();
    }

During editing make sure to re-bind your gridview with the datasource before you call DataBind();

You should have something like:

GridViewDocuments_Search.EditIndex = e.NewEditIndex;
GridViewDocuments_Search.DataSource = ???// set the datasource
GridViewDocuments_Search.DataBind();
