Delete all rows in a RadGrid with Javascript

Hello.

I need to delete all rows of a datagrid from client side. I have the following javascript code:

******************************************
            var masterTable = $find("<%= RadGrid1.ClientID %>").get_masterTableView();

            var numRows = masterTable.get_dataItems().length;
            for (i = numRows-1; i >= 0 ; i--)
            {
                masterTable.deleteItem(masterTable.get_dataItems()[i].get_element());
            }

******************************************

In the begining it worked fine, but if I put the radgrid into an updatePanel, it only works for the first row to delete. With the second row, I get this error:

'this.get_element().tBodies' is null or is not an object

I need the radgrid into an update panel in order to perform another tasks server-side using Ajax.

Any idea? Is there another way to delete all rows in a radgrid client-side?

Thanks in advance.

RadGrid not entering in edit mode.

Hi, I'm using RadGrid to show my data.
I programmatically assign the DataSource to the DataGrid
And I'm using almost only TemplateColumn.
And I'm using the EditFormTemplate to define the template for editing (because I need flexibility).
But now, the Grid is not entering in edit mode... I tried a lot of methods.. using CommandName = "Edit" or by using Item.Edit = true or using the EditIndexes Collection... but none of them worked...
Can you help me?
Here the Grid declaration:

    
            <rad:RadGrid ID="articlesGrid" runat="server" AllowPaging="true" AllowSorting="false"

How to get filter type/value pair for more than one column filter in custom data load

How can all the filtered types and values from a grid view? In the grid view, we want to provide the flexibility to filter the result by more than one column. We are using custom data source to load the grid. The below URL helps to identify the last selected filter type and value (for example col.5).

http://www.telerik.com/help/aspnet-ajax/grdoperatewithfilterexpression.html

But I’m interested to know ALL the previously selected (for example Col 1, Col 2, and Col 3) filter type and value

I’ve contacted the support and they have not given me the direct (appropriate) answer. Could any one help me?

RadGrid CSS problems. Header and row moved too far to the right.

I am having a problem with my RadGrid control. It appears that the header line, one of the rows and some of the text is shifted all the way over to the right to the point where it's past the right border area. How can I fix that? See the link for a picture. Thanks!

Filtering a column using DataFormatString

I have several columns in a instance of RadGrid using a DataFormatString to display currency with the decimal values removed (i.e. {0:c0}).

When a user attempts to filter on any of these columns using the "Equals" filter option, nothing is returned. I presume this is because the underlying data contains the decimal values which is what RadGrid is filtering on.

Is there a recommended way of handling this scenario?

Creating grid in code: problem with binding...

Help...

I am trying to create a relatively simple (but generic) report page.
Eventually, it calls a stored procedure (defined dynamically) that may return one or more recordset(s).

For each recordset, I want to create a simple grid that I simply bind to my dataset.

The user specify one or more criteria and press a button, at which time I try to create my grid(s).

My code, called from within the Button Click method looks like this (phReport is a PlaceHolder control)

    
                    public void BuildAGrid(SqlDataReader reader)  
        
                    {  
        
                        RadGrid grid = new RadGrid {DataSource = reader};  
        
                        grid.EnableViewState = false;  
        
                        grid.DataBind();  
        
                        phReport.Controls.Add(grid);  
        
                    }

The Grid shows and contains the right columns BUT shows "No records to display".

Initially, I had left EnableViewState as default (true) for both the PlaceHolder and the dynamically created grid and it showed the records when pressing the button a second time (I suppose the rows were then coming from the ViewState somehow as it seemed to hold the data).

The various articles I found say to create the grid in the Page_Init event but mine need to respond to the button click...

Any idea what I am doing wrong, or what I should do?

Many Thanks

Eric

confirm on header control click

I have a header control:

                             
            <HeaderTemplate>         
            <asp:LinkButton runat="server" ID="lbSelectAllItems" Text="Select All" CommandName="SelectAllItems" CommandArgument="qualification" ></asp:LinkButton>         
            </HeaderTemplate>         

I tried to add a javascript function in "OnClientClien" property to confirm action.

OnClientClick='return ConfirmSelectItem()'

when I click on the linkbutton at run time i get javascript error "object expected".

any idea what I am doing wrong?

thanks in advance

RadGrid Parameter Datasource

Hi,

I was wondering if any one could help me. This is the setup:-
SQL Datasource:-

    
            <asp:SqlDataSource ID="GridSqlDataSource" runat="server" ConnectionString="<%$ ConnectionStrings:connect %>" 
        
                                    SelectCommand="FilterProcMainv2" SelectCommandType="StoredProcedure">  
        
                                    <SelectParameters> 
        
                                        <asp:Parameter Name="owner" Type="Int32" /> 
        
                                        <asp:Parameter DefaultValue="7" Name="team" Type="Int32" /> 
        
                                    </SelectParameters> 
        
                                </asp:SqlDataSource>

Part of the Grid:-

    
            <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False" DataSourceID="GridSqlDataSource" 
        
                                    GridLines="None" AllowFilteringByColumn="True" AllowPaging="True" AllowSorting="True" 
        
                                    PageSize="15" ShowGroupPanel="True">  
        
                                    <MasterTableView DataSourceID="GridSqlDataSource" DataKeyNames="work_request_pk">  
        
                                        <Columns>

The grid has a number of filter columns dates and combo boxs with their own datasources. The grid loads with out any problems if I set it to datasource with out any paremeters.

I've checked my sql and it works fine, I've debugged the stored procedure and its returning the results I want.

if anyone could help or point me in the right direction it would be a great help.

Thanks
