LinkButton inside RadGrid

I have a PagerTemplate in my RadGrid. Inside is a LinkButton that is used to trigger the grid's ItemCommand event when the value of the dropdown containing the pages changes.

<

PagerTemplate>
<table border="0" cellpadding="2" cellspacing="0" style="height: 20px" align="right">
<tr>
<td valign="baseline">
<%# ((int)DataBinder.Eval(Container, "OwnerTableView.CurrentPageIndex")+ 1) * (int)DataBinder.Eval(Container, "Paging.PageSize") - 4%>

-

<%

# ((int)DataBinder.Eval(Container, "OwnerTableView.CurrentPageIndex") + 1) * (int)DataBinder.Eval(Container, "Paging.PageSize") - 5 + (int)DataBinder.Eval(Container, "Paging.Count")%> of

<%

# DataBinder.Eval(Container, "Paging.DataSourceCount")%>
|
<asp:LinkButton CssClass="pagination" ID="lbPrev" Enabled='<%# (int)DataBinder.Eval(Container, "OwnerTableView.CurrentPageIndex") !=0 %>' CommandName="Page" CausesValidation="false" CommandArgument="Prev" runat="server">
<%=Resources.Resource.strPrev_Paging%></asp:LinkButton>

|

</td>

<asp:LinkButton CssClass="pagination" ID="LinkButton4" runat="server" CommandName="CustomChangePage"></asp:LinkButton>
</td>
<td valign="baseline">
|
<asp:LinkButton CssClass="pagination" ID="lbNext" Enabled='<%# (int)DataBinder.Eval(Container, "OwnerTableView.CurrentPageIndex") != (int)DataBinder.Eval(Container, "Paging.PageCount")-1 %>' CommandName="Page" CausesValidation="false" CommandArgument="Next" runat="server">
<%=Resources.Resource.strNext_Paging%></asp:LinkButton>

</td>
</tr>
</table></PagerTemplate>

It worked fine until recently when I encountered an "Object doesn't support this property or method." error message when I select from the dropdown. In View Source, the entire grid is not visible. I tried using Style["Display"] instead of the Visible property but I still encounter the same error.

What can I do?

My problem is when I click the btnUpdate button the Item_Created Sub is run first resetting any values that where changed. I've tried initiating my template forms in the edit_command sub but they don't exist yet. Is it possible to do what I want?

RadGrid javascript error

Hi!

I have a RadGrid with some data. I group this data for some criteria (I call, p.e., tableori).

    
            GridGroupByExpression expression = new GridGroupByExpression(); 
        
            GridGroupByField gridGroupByField = new GridGroupByField(); 
        
            //Add select fields (before the "Group By" clause) - Campo de ruptura 
        
            gridGroupByField = new GridGroupByField(); 
        
            gridGroupByField.FieldName = "tableori"; 
        
            gridGroupByField.FormatString = "<strong>{0}</strong>"; 
        
            expression.SelectFields.Add(gridGroupByField); 
        
            //Add a field for group-by (after the "Group By" clause) - Agrupación 
        
            gridGroupByField = new GridGroupByField(); 
        
            gridGroupByField.FieldName "tableori"; 
        
            expression.GroupByFields.Add(gridGroupByField); 
        
            assigGrid.MasterTableView.GroupByExpressions.Add(expression); 
        
            assigGrid.MasterTableView.ShowGroupFooter = true;

The trouble is when I try to change the message at GroupHeader. When I try to sort the grid or paging it, I have the exception "Session state can only be used when enableSessionState is set to true, either in a configuration file or in the Page directive"; but if I comment the lines inside the if otpion of GridGroupHeaderItem works fine.

    
            protected void assigGrid_ItemCreated(object sender, GridItemEventArgs e) 
        
            { 
        
                try

                        defObjeto = wc.GetObjetoAsignacionH(objeto, idioma); 
        
                    } 
        
                    if (e.Item is GridGroupHeaderItem) 
        
                    { 
        
                        GridGroupHeaderItem item = (GridGroupHeaderItem)e.Item; 
        
                        // Los datos que afectan a esta agrupación (criterio(s) de agrupación y subtotales si los hubiere) 
        
                        DataRowView groupDataRow = (DataRowView)e.Item.DataItem; 
        
                        int colSpan = item.Cells[1].ColumnSpan; 
        
                        item.Cells.RemoveAt(1); 
        
                        TableCell tc = new TableCell(); 
        
                        tc.ColumnSpan = colSpan; 
        
                        tc.HorizontalAlign = HorizontalAlign.Left; 
        
                        tc.Text = "My title"; 
        
                        item.Cells.Add(tc); 
        
                    } 
        
                } 
        
                catch (Exception exc)

                } 
        
            }

Any ideas or suggestions to skip this problem?

Grid Paging Problem exists

2 days before i asked for the following problem -
im using alphabet paging in Radgrid, whenever we do paging the grid height increases or decreases as according to no. of records and pager(which is showing alphabets) doesn't remain in one location i.e i want it should get freezed at one location so that it does't look like flickering. is it possible?

To resolve this problem i tried setting the Height of the Grid to a fixed value, but by applying this im facing another problem is that grid header, body and footer height increase if no. of records is less than page size. is there any other solution for this?

[Solved] GridTemplateColumn : get column reference in InstantiateIn method

Hi all,

In my app, I have a RadGrid which I built dynamically by adding coulmns in the page_init()... One column is a GridTemplateColumn with a custom ItemTemplate. Everything works fine but I would like to know if there a way to get the column(GridTemplateColumn) reference in InstantiateIn method ?

    
            public class myTemplate : ITemplate     
        
            {     
        
                void ITemplate.InstantiateIn(Control container)      
        
                {     
        
                    //want to get the reference of column here  
        
                }     
        
            }

How to make theme(or CSS) apply only to toolbar but not RadEditor main box?

I plan to make a RichEditor on ASP.NET, Design mode only.
Ideally, the main box border should always be a simple silver color 1px border, always. When user click the text area, the tool bar should show a band of icons.

I can make the main box with simple silver 1px border either in editing or non-editing by this:

EditModes="Design"

EnableResize="False" EnableTheming="False" Height="600px" Skin="Vista"

ToolbarMode="ShowOnFocus" Width="500px" BorderColor="Silver" BorderWidth="1px" EnableAjaxSkinRendering="True" EnableEmbeddedBaseStylesheet="True" EnableEmbeddedSkins="False" ToolsWidth="500px" BorderStyle="Solid"

but this also makes the toolbar looks weired (no icons anymore,but tooltips still there).
How do I make the toolbar still show properly but only main box without skins?

Thanks a lot

[Solved] FileName, showing full path not mapped drive letters?

Hi,
I'm using the following code to return the name of a document and the full path of a selected document:

fileName =

Me.RadUpload1.UploadedFiles(0).GetName()

filePath =

Me.RadUpload1.UploadedFiles(0).FileName

Question: If the filePath is something like X:\SomeFolder\SomeDocument.xls, for which X points to a mapped drive like \\servera\
How can I return the filePath with the actual server name? instead of the mapped drive letter?

So I want: \\servera\SomeFolder\SomeDocument.xls,
instead of X:\SomeFolder\SomeDocument.xls,

thanks

Radgrid disappears in Firefox 3

Hey there folks, hopefully someone can lend me a hand because I've been staring at this too long.

I'm using DNN, and have a module that uses RadSlidingPanes/RadPane/RadSlidingZone/RadSplitter.

On the left are tabs that slide out with different options.

On the right side is a RadGrid.

In IE7, Safari 3, Opera 9.6, and Chrome, it works fine.

In Firefox 3, the Radgrid appears for a split second and then disappears never to be seen again, and I have no idea why.

Does anyone have any idea?

By the way, I'm using the following DocType:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">

I'm using this DocType because going into the "way-back" machine (a year ago or so), this was the only DocType that allowed (the old RadControls) to display in DNN correctly. Could the DocType be the problem now?

Thanks for your Help!

Kuba
