I have created a RadGrid dynamically and added it to a placeholder at Page_Init event.

I'd need to add a custom button to the CommandItem and for this I've tried many scenarios and none of which has worked properly:

1) I added the custom button at RadGrid_ItemCreated event. The button appears. When it's clicked, it posts back, however, its click event handler is never raised. why? how to fix it?

My button is a normal ASP.NET button:

private Button CreateExportToPdfButton()
        {
            var result = new Button();
            result.ID = "btnExportToPdf";
            result.Click += ExportToPdfButtonClick;
            result.CssClass = "rgExpPDF";
            result.CommandName = "ExportToPdfCustomCommand";
            result.Attributes["title"] = "Export to Pdf";
            return result;
        }

Also I tried managing it in the ItemCommand event when the button is clicked: 

protected void RadGrid1_ItemCommand(object sender, GridCommandEventArgs e)       

{

    if(e.CommandName == "ExportToPdfCustomCommand")

    {

        //my code here

    }

}

but ItemCommand event doesn't get raised either when the button is clicked.

2) I added the custom button at RadGrid_MasterTableView_Load. The button appears and when it's clicked, it posts back and click event is raised as expected which is great. As soon as sorting is enabled on the RadGrid and a column header is selected to be sorted, the sorting happens however my custom button disappears. Why? how to fix it?

3) On RadGrid_MasterTableView_Init; behaves similar to #2

4) On RadGrid_MasterTableView_PreRender; behaves similar to #1

5) On RadGrid_Init, behaves similar to #2

6) Another possible approach comes to mind is to create a new CommandItemTemplate: http://www.telerik.com/help/aspnet/grid/grdcommanditemtemplate.html

in which case, the click event and itemcommand events are raised properly.

But there is an issue with this approach that it would be more complex as I'm using the built-in Export to Word and Excel functionalities of RadGrid currently. so not sure how to add these 2 to the CommandItemTemplate this way?

I'd rather making the previous approaches working if possible.

Your help is very much appreciated on any of these approaches.

Hello,

I try to implement custom filter control like here. I put a textbox and button into template column and everything now shows fine in filter row. But I need to set custom button which will contain fully custom filter menu. I want it to display when I press the button and send a filter command  when menu item is selected. But right now I can't event start built-in filter menu. I tried to add button onclick event like on your demo page, i.e.
$find("RadGrid1")._showFilterMenu("RadGrid1_ctl00", "ContactName", event); return false; __doPostBack('RadGrid1$ctl00$ctl02$ctl02$Filter_ContactName','')
but I always get a JS error  here:

this._buildFilterMenuItemList(this._filterMenu,f._data.FilterListOptions,f._data.DataTypeName,f._data.CurrentFilterFunction,f);

If I translate it to English, it's going to be like "Cannot get a value for _data; it's not defined or has a null value". Something like this.
So I have 2 questions:
  a. Is this possible to display built-in filter menu when clicking on custom button inside a filter template?
  b. Is this possible to built a fully custom menu and make it work the same way as built-in?
Thank you.

Hi,

I am trying to load my second combobox based on the item selected from first combobox. The code goes something like this

Aspx page

<telerik:RadComboBox ID="DepartmentDD" runat="server" OnItemsRequested="DepartmentDD_ItemsRequested" OnClientSelectedIndexChanging="LoadSection" OnClientItemsRequested="ItemsLoaded" width="175px"/>


<telerik:RadComboBox ID="SectionDD" runat="server" OnItemsRequested="SectionDD_ItemsRequested" OnClientItemsRequested="ItemsLoaded" width="175px" />   


function ItemsLoaded(combo, eventarqs) {

    var secCombo = $find("SectionDD");
    if (combo.get_items().get_count() > 0) {
        combo.set_text(combo.get_items().getItem(0).get_text());
        combo.get_items().getItem(0).highlight();
    }
                    combo.showDropDown();
}


function LoadSection(combo, eventarqs) {
    var seccombo = $find("SectionDD");
    var item = eventarqs.get_item();

    seccombo .set_text("Loading...");
    seccombo .requestItems(item.get_value(), false);
}


---------

CS page


 protected void Page_Load(object sender, EventArgs e)
{

    LoadDepartment();

}
      

    protected void LoadDepartment()
        {
        //Loads department to DepartmentDD
        }


        protected void DepartmentDD_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e)
        {
            LoadDepartment();
        }

        protected void SectionDD_ItemsRequested(object o, RadComboBoxItemsRequestedEventArgs e)
        {

            LoadSection(Convert.ToInt16(deptid));
        }

        protected void LoadSection(int deptId)
        {
            
          //Loads section to SectionDD
        }


The problem is when I reach SectionDD_ItemsRequested after selecting item from first combo the control is firing OnInit method which loads the deparment againg :(.

Where am I going wrong?

Hello,
Can you please tell me how do I exactly call fireCommand on filtering? According to this help page I have to pass 4 parameters, like
fireCommand("Filter", colName, expression, function).
According to some pretty old forum post, I have to pass 2 parameters, like
fireCommand("Filter", colName + "|" + expression + "|" +  function)
I tried everything but I always get Index out of bounds error. Page_Load event fires correctly  but it never comes into ItemCommand event.
Calling mastertableview.filter() function will not fire postback. So what should I do to initiate filtering from client side?

I came accross this post, which seems to be the issue I am having, my question is how do you do the following to fix the problem?

You will need to be sure that the chart httphandler is served by the same machine, which served the page.

Looking for a way to access or store an object from a Linqdatasource foreign key.

I have a Radgrid using a Linqdatasource with a nestedviewtemplate and a RadTabStrip/RadMultiPage. I would like to populate a RadGrid on one of RadMultilPage with the foreign key data from the Master RadGrid.

Is this possible?

Hi,

I am using the telerik.Web.UI.dll with version 2010.1.415.35.

I am having problem with the Rad Grid filter menu in this version. When ever I click on filter menu it firstly it shows only "Contains" button
and secondly, after clicking on filter button it gives a java script error of parsing as Parsing problem for Enum "Sys&Enum&Parse"(typeof()). something like this.

Please note that, earlier I was using the telerik DLL version of 2008 which I then replaced with 2011.2.712.35. This worked fine with no problem except with change in design. Now, I have removed this and replaced it with 2010.1.415.35 and the above error has occurred.

Can anyone help me or suggest me on this issue. Its urgent.

Thanks.

Hi Telerik team, I've been working on a solution requiring that the columns order can be editable, the RadGrid control we are using is on a SharePoint Webpart. We have an editor part where the page manager can edit the order of the columns. When the editing of the webpart is saved & closed the new data is passed to the RadGrid control to update. All the functionality works as expected except the order. This order is set programatically to the columns as it is configured on the editor part, we checked that the column.position is set correctly but the RadGrid is not re-ordering the columns when the Save & Close its done.
We want some support to make this work if possible.

Fun Fact: If any of the filters, grouping, or re order is done on the control (generating a Post-back) all the columns re-order with the specified order in the editor part.

Thanks in advance!!

Here is our code where we set the position of the columns:

Column column = new Column();
                    column.Name = ((Label) repeaterItem.FindControl("lblColumnName")).Text;
                    column.Id = GetColumnId(column.Name);
                    column.Display = ((CheckBox) repeaterItem.FindControl("chkDisplay")).Checked;
                    column.Position = Convert.ToInt32(((DropDownList) repeaterItem.FindControl("ColumnsDropDown")).SelectedItem.Text);
                    colunns.Add(column);

We set these attributes for each columns displayable on the RadGrid control.
