Forms Data Controls :: Gridview RowDataBound Event - Set Default Value

May 17, 2010

When 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.

Forms Data Controls :: GridView's RowDataBound Event Fired Twice?

Apr 20, 2010

I 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, 2010

Why 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').

void Master_QueryButton_Click(object sender, EventArgs e)
{
RetiredEmployeeDataContext db = new RetiredEmployeeDataContext();
NameValueCollection nvcQueryKeyValue = getNVCQueryKeyValue();
Expression<Func<RetiredEmployee, bool>> searchPredicate = getLambdaExpr(nvcQueryKeyValue);
IQueryable<RetiredEmployee> retireds = db.RetiredEmployees;
Expression expr = Expression.Call(typeof(Queryable), "Where",
new Type[] { typeof(RetiredEmployee) }, Expression.Constant(retireds), searchPredicate);
IQueryable<RetiredEmployee> query = db.RetiredEmployees.AsQueryable().Provider.CreateQuery<RetiredEmployee>(expr);
List<RetiredEmployee> employeeList = new List<RetiredEmployee>(query);
List<RetiredEmployeeEO> employees = new List<RetiredEmployeeEO>();
foreach (RetiredEmployee employee in employeeList)
{
RetiredEmployeeEO employeeEO = new RetiredEmployeeEO();
employeeEO.MapEntityToProperties(employee);
employees.Add(employeeEO);
}
cgvEmployees1.ListClassName = typeof(RetiredEmployeeEOList).AssemblyQualifiedName;
cgvEmployees1.LoadMethodName = "LoadFromQuery";
cgvEmployees1.LoadMethodParameters.Clear();
cgvEmployees1.LoadMethodParameters.Add(employees);
cgvEmployees1.DataBind();
}
protected void cgvEmployees1_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
//Add the edit link to the action column.
HyperLink editLink = new HyperLink();
if (((BasePage)this.Page).ReadOnly)
{
editLink.Text = "View";
}
else
{
editLink.Text = "Edit";
}
editLink.NavigateUrl = "employee.aspx" + EncryptQueryString("id=" + ((RetiredEmployeeEO)e.Row.DataItem).ID.ToString());
if(e.Row.Cells[0].Controls.Count==0)
e.Row.Cells[0].Controls.Add(editLink);
//Add checkbox to display the isactive field.
CheckBox chkActive = new CheckBox();
chkActive.Checked = ((RetiredEmployeeEO)e.Row.DataItem).liveOrDead;
chkActive.Enabled = false;
if(e.Row.Cells[24].Controls.Count==0)
e.Row.Cells[24].Controls.Add(chkActive);
if (((RetiredEmployeeEO)e.Row.DataItem).gender.Equals((byte)1))
e.Row.Cells[2].Text = "Male";
else
e.Row.Cells[2].Text = "Female";
if (((RetiredEmployeeEO)e.Row.DataItem).retiredOr.Equals((byte)1))
e.Row.Cells[14].Text = "Retired1";
else
e.Row.Cells[14].Text = "Retired2";
if (((RetiredEmployeeEO)e.Row.DataItem).birthday.Equals("1753-01-01"))
e.Row.Cells[3].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).dayToEmployed.Equals("1753-01-01"))
e.Row.Cells[6].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).dayRetired.Equals("1753-01-01"))
e.Row.Cells[7].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).dayParty.Equals("1753-01-01"))
e.Row.Cells[13].Text = "";
if (((RetiredEmployeeEO)e.Row.DataItem).daytoassign.Equals("1753-01-01"))

Forms Data Controls :: Access GridView PageIndex In Rowdatabound Event?

Feb 5, 2010

How do I access GridView Page Index in RowDataBound event? I am assigning PageIndex to hyperlink on the gridview, for this I was planning to use "GridView1.PageIndex" in rowdatabound event. Problem is when I got second page in gridview (10 rows per page), the first row in the page shows page index as "0" and from second row it becomes 1. And if I goto third page, the first row in the page shows page index as "1" and from second row it becomes 2.

Forms Data Controls :: Rowdatabound Event Of A Gridview Loses Its Value While Editing?

Feb 5, 2011

I 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.

Forms Data Controls :: Conditionally Hide 2 LinkButtons In A Grigview?

Aug 26, 2010

I'm trying to conditionally hide 2 link buttons within a Gridview(gvPosts), ModifyButton and DeleteButton. I want the two buttons to hide in every row where the currently logged on Username is not the same as the Username in gvPosts' lbEmpID, a LinkButton control in the same row. Unfortunately the code is hiding the buttons in every row, including the one where lbEmpID.text = Profile.Username. My code is below, what am I doing wrong?

Dim lbtn As LinkButton
For Each rowItem As GridViewRow In gvPosts.Rows
lbtn = DirectCast(rowItem.Cells(0).FindControl("lbEmpID"), LinkButton)
If lbtn.Text <> Profile.UserName Then
Dim Modify As LinkButton
Dim Remove As LinkButton
For Each rowItem1 As GridViewRow In gvPosts.Rows
Modify = DirectCast(rowItem1.Cells(0).FindControl("ModifyButton"), LinkButton)
Remove = DirectCast(rowItem1.Cells(0).FindControl("RemoveButton"), LinkButton)
Modify.Visible = False
Remove.Visible = False
Next
End If
'If chk.Checked Then
'Response.Write(chk.ClientID + "<br />")
'End If
Next
