hi when i allow sorting on gridview i recieve this error message
The GridView 'GridView1' fired event Sorting which wasn't handled.
i also add this event in gridview and add this code
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
GridView1.Sort(e.SortExpression, e.SortDirection);
}but infinite loop occurs and page give error
Please tell me solution of this problem
Thanx
|

you have to AllowSorting="true" set for the GridView and therefore you need to have event handler for its Sorting event
Hope this may be your problem.

You only need to handle the sorting event if there is some special case for sorting. The default mechanism should be sufficient for sorting on the column header.

try with this code:
protected override void OnSorting(GridViewSortEventArgs e)
{
if (AllowMultiColumnSorting)
e.SortExpression = GetSortExpression(e);
base.OnSorting(e);
}

You need to refresh the data source so that it's sorted accordingly.

Where is GetSortExpression(e); How is this helpful?

You're getting an infinite loop because calling GridView1.Sort will fire the GridView1_Sorting event (I'm sure you figured that out aleady)
I think GridView will only sort automatically if you're using one of the new DataSource providers, like SqlDataSource, XmlDataSource, ObjectDataSource, etc. (I could be wrong about that, but so far that's been my experience).
You could try something like:
private void FillGrid( string sortExpression, SortDirection sortDir )
{
string sort = sortExpression + " " + (sortDir == SortDirection.Descending ? "desc" : "" );
DataTable dt = GetDataTableFromSomewhere();
DataView dv = new DataView(dt, "", sort, DataViewRowState.CurrentRows );
GridView1.DataSource = dv;
GridView1.DataBind();
}
protected void GridView1_Sorting(object sender, GridViewSortEventArgs e)
{
FillGrid(e.SortExpression, e.SortDirection);
}
Viewstate could become an issue doing it this way. I typically disable view state on grids though, but then you have to work around a bunch of other issues.

I add a asp Checkbox in the Datagrid ItemTemplate and HTML checkbox in Header Template.In the datagrid am loading the images and the path from the server folder.am loading all the images in the page load event.page load event as follows
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
DataSet ds = new DataSet();
DataTable dt = new DataTable("Photos");
dt.Columns.Add("Photos", Type.GetType("System.String"));
foreach (string Files in Directory.GetFiles(System.Web.HttpContext.Current.Server.MapPath("Photos"), "*.jpg"))
{
dt.Rows.Add(Files);
}
ds.Tables.Add(dt);
this.dgPhotos.DataSource = ds;
this.dgPhotos.DataBind();
}
}
All the images am getting in the Datagrid.but my problem is,i want to delete the checked images.the delete code as follows
foreach (DataGridItem item in dgPhotos.Items)
{
CheckBox chkBox = (CheckBox)item.FindControl("chkItem");
if (chkBox.Checked)
{
File.Delete(item.Cells[2].Text);
}
}
while clicking the Header template checkbox it will select all the Item template checkbox[Javascript function],all the sub checkbox are checking fine.but the problem is i will not get the checked state in the delete event,getting checkbox.checked=false.so i cannot delete the images.in the page load event if am not using !Postback and if i select one by one in the Itemtemplate checkbox i could delete,i will get checked=true but if select header check will not get.what is the problem.Is there any solution for this.

Have you solved this problem?

Hi All
I have a gridview with 2 bound columns and 3 TemplateField columns containing 3 checkboxes. Iam not being able to display the check boxes correctly although thrie values are correct in the database.
Any Ideas?

I recommend fixing your code so it works.
For a more detailed answer, try posting some code, and explaining what you mean by 'unable to display correctly'

I have solved a part of it by binding the check boxes and giving them values from database. But there still is a bug which is when binding a certain type with no data, the gridview is not appearing while i need it to appear with empty checkboxes.
Thanks in advance.

dim ds as new dataset<br />
ds = DBUsers.Pages_Select(DDLTypes.SelectedValue)<br />
Dim tblPages As DataTable = New DataTable<br />
tblPages = ds.Tables(2)<br />
DGPages.DataSource = tblPages<br />
DGPages.DataBind()
stored procedure:
select * from usersAccess ua left outer join UsersOptionsAccessPages uap on ua.UsersOptionsAccessPages_ID =uap.UsersOptionsAccessPages_ID where ua.usersOptionsAccessLevels_Id= @TypeId

I'd imagine you need to bind the grid so it calls a codebehind method that won't blow up if there's no data for the checked property

He didn't mention anything about an error. If you haven't figured it out, having the most posted with the lowest score doesn't get you any prizes. Just go away.
