[Solved] Grid Filtering Errors or no Filtering at all...

Hi all,

Long time lurker first time poster.

I'm developing a report using the RadGrid control (full version) and one of the requirements is that it must be possible to filter the rows. Previously before using the RadGrid I'd obviously just filter the data source then re-render the html table but.... you know RadGrids are pretty and support so much functionality out of the box I thought what the hell?

Anyway - obviously I'm posting because its not gone too swell.

Initially I got the Expression Expected error... all fine and good, tons of threads with the answer set EnableLinqExpressions="False". Did that and sure enough the error disappeared.... however no filtering appeared? As in after the postback was finished no filtering had been applied. I was kind of under the impression from the Basic Filtering Tutorial that it should be a pretty much out of the box "hey presto no need to manually make all the filters" deal? Starting to think that's not the case.

Anyway - details: -

I'm using the OnNeedDataSource event, the code currently looks -roughly- like: -

protected void MyGrid_OnNeedData(object sender, GridNeedDataSourceEventArgs e)

{

...General getting data stuff...

MyGrid.DataSource = MyData;

}

With MyData being a List<MyObject>.

Now there WAS something about using the OnNeedDataSource event in the basic filtering tutorial. I didn't think it was 100% clear though to be honest as it talked about "checking" the FilterExpression in the OnNeedDataSource event - is this actually implying that if you use this method of data binding you do have to manually do all the filtering? As you might have guessed I'm rather hoping thats NOT the case heh.

Anyway - appreciate any input. Thanks!

Getting "an error occurred processing a web or script resource request" for contextMenu.gif

I've been trying to debug this error that's been popping up in the event viewer and I can't figure out what's causing it. There are some oddities happening on the site, but I'm not sure (and somewhat doubt) this is the reason, but I'm just going through the process of elimination now.

Anyway, this is what I get: An error occurred processing a web or script resource request. The requested resource 'pTelerik.Web.UI.Skins|Telerik.Web.UI.Skins.Common.Metro.contextMenu.gif' does not exist or there was a problem loading it.

Can anyone point me in the right direction and help me troubleshoot this? The version of RadControls that I'm using is 2013.1.220.45.

Thank you,
Andrew

Unknown server tag 'telerik:RadHtmlChart' (Problem in dll)

Hi Telerik Team,

When i add RadHtmlChart, I am faced the error
Unknown server tag 'telerik:RadHtmlChart'

then by following this link
http://www.telerik.com/community/forums/aspnet-ajax/htmlchart/unknown-server-tag-telerik-radhtmlchart.aspx
i updated the controls to newer version. then the RadHtmlChart works fine.

But now the problem is,
after updation, the itemCommand in the RadGrid are showing error.
here is my code.

protected void rgFiles_ItemCommand(object source, GridCommandEventArgs e)

{

int index = int.Parse(e.Item.ItemIndex.ToString());

GridDataItem item = (GridDataItem)FileTable.MasterTableView.Items[index];

item.Selected = true;

row_id = int.Parse(item["id"].Text);

string File_name = item["Name"].Text;

Label2.Text = File_name;

LiteralControl litCon = new LiteralControl();

litCon.Text = "<iframe name='attachIFrame' id='runtimeIFrame' frameborder='solid' word-wrap='normal' scrolling='auto' height='100%' width='400px' src='RiskManagementStrategyFiles/" + File_name + "' style='left:0; background-color: beige;'></iframe>";

Panel1.Controls.Add(litCon);

}

visible property for id is "false" in .aspx page

Error
Exception Details: System.FormatException: Input string was not in a correct format.
Source Error:


            Line 219:        item.Selected = true;
Line 221:        row_id = int.Parse(item["id"].Text);
Line 223:        string File_name = item["Name"].Text;

this error is solved, if we give visible property = "true" in .aspx page
SortExpression="id" UniqueName="id" Visible="true" HeaderStyle-CssClass="hide" ItemStyle-CssClass="hide">
------------------------
//CSS
.hide { display:none; }

but if i do like this, I have many RADgrids in my project. I need to change in all the grids.

(Again if i repalce the dll in Bin folder with the old dll, then the grid works fine but RadHtmlChart showing the same error)
Please help me....

Please give solution for this

Thanks in advance
--Alex

How to dynamically add columns to a hierarchical grid

I'm trying to figure out how to dynamically add columns to a hierarchical/nested grid in a RadGrid. Which columns need to be created are determined by a Check Box List control. And I only know for sure which columns to add after the RadGrid_DetailTableDataBind is called.

I can get it all to work if I set AutoGenerateColumns to TRUE. But of course I need to make two of the columns (if they are selected) TemplateColumns. Which is why I have to dynamically add the columns.

To me it looks like I have two choices (neither of which I could make work). 1) Add the columns to a statically created hierarchical grid. Or 2) Create the hierarchical grid dynamically and then the columns.

For the first option after the RadGrid_DetailTableDataBind is invoked, a datatable is populated from a database query. After the datatable (which is going to be the datasource) is generated I call the following routine (with datasource table as the one calling parameter).

Sub AddColumnsToGrid(ByVal ResultTable As DataTable)

Dim bc As GridBoundColumn

Dim dgOSEvent As GridTableView = RadGrid1.MasterTableView.DetailTables(0)

dgOSEvent.Columns.Clear()

'Dim dgOSEvent As GridTableView = New GridTableView(RadGrid1)

bc = New GridBoundColumn()

bc.DataField = "% of Total"

bc.HeaderText = "% of Total"

bc.ItemStyle.HorizontalAlign = HorizontalAlign.Center

bc.DataFormatString = "{0:p}"

dgOSEvent.Columns.Add(bc)

bc = New GridBoundColumn()

bc.DataField = "Count"

bc.HeaderText = "Event Count"

bc.ItemStyle.HorizontalAlign = HorizontalAlign.Center

bc.DataFormatString = "{0:###,###,###}"

dgOSEvent.Columns.Add(bc)

For Each dc As DataColumn In ResultTable.Columns

If dc.ColumnName <> "COUNT" And dc.ColumnName <> "% of Total" Then

If dc.ColumnName = "SOURCE" Or dc.ColumnName = "DESTINATION" Then

Dim tc As GridTemplateColumn = New GridTemplateColumn()

tc.HeaderTemplate = New DataGridTemplate(ListItemType.Header, dc.ColumnName)

tc.ItemTemplate = New DataGridTemplate(ListItemType.Item, dc.ColumnName)

tc.ItemStyle.HorizontalAlign = HorizontalAlign.Center

dgOSEvent.Columns.Add(tc)

Else

bc = New GridBoundColumn()

bc.DataField = dc.ColumnName

bc.HeaderText = dc.ColumnName

If dc.ColumnName = "Description" Then

bc.ItemStyle.HorizontalAlign = HorizontalAlign.Left

Else

bc.ItemStyle.HorizontalAlign = HorizontalAlign.Center

End If

dgOSEvent.Columns.Add(bc)

End If

Next

End Sub

I can post the code for DataGridTemplate, but I don't think that's the problem here. I suspect that I'm getting something more fundamental wrong.

The results I get when running this code is I do get a grid row for each record in my results. Their headers are blank and the contents of the GridBoundColumn are: System.Data.DataRowView. The template columns are blank.

My attempt at the 2nd approach was even less successful. So I'll need more direction if this turns out to be the best way to go.

Thanks for any help on this.
