Query Regarding Rowdatabound Event In Gridview C#
Mar 31, 2011When u have a gridview(lets say gridview1) and u associate an event
OnRowDataBound = "gridView1_RowDatabound"
and u usually start the event method as follows
protected void gridView1_RowDatabound(object sender, GridViewRowEventArgs e){
if (e.Row.RowType == DataControlRowType.DataRow){
do something..
}
}
Why do u have to check again if the row is data row, as i understand it gridview1_rowdatabound event occurs only when the rows are getting bound by the datasource u supplied. Why do u perform again this additional checking ?

Forms Data Controls :: Gridview RowDataBound Event - Set Default Value
May 17, 2010When a Gridview row is in edit, I need to default an empty textbox to today's date. I am close, but the defaulted date is is not saved to the database. I can key in the date and the date is displayed and saved to the database. Even more interesting:
1. The date is defaulted to - 5/17/2010
2. If I erase the month and key the "5" back in the data is not saved.
3. If I erase the month and then change the month to "6", the data is saved to the database. If any value is changed in the date the save works.

View 3 RepliesForms Data Controls :: GridView's RowDataBound Event Fired Twice?
Apr 20, 2010I have a very simple asp.net page, just some buttons and one GridView on it. The logic is a user click the QUery button,then the button click event was trigured to populate the gridview with data queried from database via LINQ. for a user friendly interface, in RowDataBound event, I visit every row, change a boolean value into checkbox represention. But it seem that the RowDataBound run twice, because the checkboxs were inserted twice for every row in one cell. so why? the source code snippet as follow:
protected void btnSelect_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
GridView1.DataSource = db.ENTUserAccountSelectAll();//userAccounts;
GridView1.DataBind();
}
protected void GridView1_OnRowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((ENTUserAccount)e.Row.DataItem).IsActive;
chkActive.Enabled = false;
e.Row.Cells[5].Controls.Add(chkActive);
}

Forms Data Controls :: Why Wasn't GridView's RowDataBound Event Fired
Apr 21, 2010Why wasn't my GridView's RowDataBound event fired? I have a masterpage on whick i have a query button, and I have a content page on which i have a customized GridView(named cgvEmployees,derived from GridView). The logic is when user click the button, the button click event triggered that search the underlying database and populate the GridView.
Everything runs great except that RowDataBound event isn't triggered. Because I have to change some cells' representations in RowDataBound event handler. I have surfed so much pages to find the answer but failed. Below is what i have already done:
1. set the autoeventwireup to true;
2. i have a cgvEmployees.bind() sentence in the button click event handler;
3. i have OnRowDataBound="cgvEmployees_OnRowDataBound" in the content page GridView tag attribute
by the way, the database query is coded by Linq Dynamic Query (please google 'dynamic Linq').

Forms Data Controls :: Rowdatabound Event Of A Gridview Loses Its Value While Editing?
Feb 5, 2011I have a Gridview with edit and update feature enabled. It displays the data correctly but when I click on the Edit linkbutton(to edit the data), I get the error "Object reference not set to an instance of an object".
I tried debugging and found that the row which I click (say editindex is 1) loses its value. I could identify this while debugging the code, when the code flow moves to the rowdatabound event, the label (or for that matter any control in the rowdatabound event) shows a null value and eventually errors out.
I am unable to figure out as to why the control specified in the rowdatabound event loses its value when editing. Note: The lost valueow data is the one which I tried editing.
I am attaching the code which I have written for the rowdatabound event.
