I have a radcombobox and in that I have placed one checkbox after databinding I want to insert one more checkbox inside that radcombobox to select all items.

<telerik:RadComboBox ID="cmbRoleName" EmptyMessage="- please select group -" runat="server"
                                     AutoCompleteSeparator="true" HighlightTemplatedItems="true"
                                    AutoPostBack="True" AllowCustomText="true" OnClientDropDownClosed="onDropDownClosing">
                                    <Items>
                                        <telerik:RadComboBoxItem Value="0" Text="-- Select All Users --" />
                                    </Items>
                                    <ItemTemplate>
                                        <table border="0" cellpadding="0" cellspacing="0">
                                            <tr>
                                                <td>
                                                    <asp:CheckBox runat="server" ID="chkRole" Text='<%#DataBinder.Eval(Container.Dataitem,"RoleName")%>'
                                                        Onclick="chkBox_Click(this)" />
                                                </td>
                                            </tr>
                                        </table>
                                    </ItemTemplate>
                                </telerik:RadComboBox>

I have tried to do this on server side like this but the problem is that two checkboxes are appearing one with text and without text. Any Help would be really appreciated.

Protected Sub CreateSelectAllUsersCheckBox()
        Dim chkSelectAllUsers As New CheckBox
        chkSelectAllUsers.Text = "Select All Users"
        chkSelectAllUsers.ID = "chk1"
        Dim radComboBoxItem As New RadComboBoxItem
        radComboBoxItem.Text = "Select All Users"  
radComboBoxItem.Controls.Add(chkSelectAllUsers)     
        cmbRoleName.Items.Insert(0, radComboBoxItem)
    End Sub

Dear Experts,

I am implementing a web application. Because the system responsiveness in for me critical I decided to use RadrGrid with Client side binding. As the table shows some related data I would implement some filter templates with combo boxes. I was spending some time in finding a demo or guidelines to implement this scenario, but I found nothing useful.

  

Can anybody address me to any demo or at least give me some guidelines.

Any help would be appreciated.

Weird behavior that just started happening after I made some code changes.

I have a tabstrip with 2 tabs and a grid inside each tab, and when I click on the filter button, the dropdown menu doesn't pop up. If I click on the other tabstrip, it reloads the other grid, and then it starts working fine if I click back on the tab  to reload it again. I am trying to figure out what is causing this, and I will let everyone know if I find out. Just wanted to know if you have any ideas what's causing this.

Hello,

I have used rad grid with insert , update option using edit form template.While Add/Edit time Depending on Radio Button Selection I need to Enable , Disable Validation. I have putted java script for show hide panels and enable , disable validation for radio button selection.  Insert , Update option works perfect when validation are enable but when i am selecting radio button option which is disabling my validation then by clicking on Insert , Update button my insertcommand and updatecommand are not working. By clicking on insert or update button it direct comes to itemcommand event not on insert or update command.

I have debug javascript there is no issue in java script. page is getting postback and rather than insert or update command it comes to item data bound and item command.

Any Idea why rad grid insert , update command not working after disabling validation?

Hi,

I use radcombox control in my page. I filled items in this combobox at page_load event. For example; items are SLOVENIA, SPAIN, SWITZERLAND..

I type only S then focus on SLOVENIA... thats ok.. But I want to focus SPAIN so I want to type second character but it doesn't allow me.

This problem occur in some clients ( Internet Explorer v 8.0.7600.16385 )

If I change browser to Firefox, there is no problem. What do I have to change settings of IE ?
I am using v.  Telerik 2009.02.0701.35

Hi

I followed the link http://www.telerik.com/help/aspnet-ajax/grdfilteringbylisttextfieldforgriddropdowncolumn.html to try to filter a drop down column as below:

                <telerik:GridDropDownColumn UniqueName="LocationID" ListTextField="LocationName"
                    AutoPostBackOnFilter="true" CurrentFilterFunction="Contains" ShowFilterIcon="false"
                    ListValueField="LocationID" HeaderText="Location" DataField="LocationID" ReadOnly="true">
                </telerik:GridDropDownColumn>
                <telerik:GridBoundColumn DataField="LocationName" HeaderText="LocationName" SortExpression="LocationName"
                    UniqueName="LocationName" Display="false">
                </telerik:GridBoundColumn>

and have the item command event handler as below:
        protected void RadGridUsers_ItemCommand(object source, GridCommandEventArgs e)
        {
            if (e.CommandName == RadGrid.FilterCommandName)
            {
                Pair command = (Pair)e.CommandArgument;
                if (command.Second.ToString() == "LocationID")
                {
                    e.Canceled = true;
                    GridFilteringItem filter = (GridFilteringItem)e.Item;
                    ((filter["LocationName"].Controls[0]) as TextBox).Text = ((filter["LocationID"].Controls[0]) as TextBox).Text;
                    command.Second = "LocationName";
                    filter.FireCommandEvent("Filter", new Pair(command.First, "LocationName"));
                }
            }
        }

The only difference is that I have not got a declared data source but binding drop down column by code:
 

        protected void RadGridUsers_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem && !e.Item.IsInEditMode)
            {
                GridDataItem item = (GridDataItem)e.Item;
                Literal litrl = (Literal)item["LocationID"].Controls[0];

                CommonDataService commonDataService = new CommonDataService();
                object dataBindingResult = DataBinder.Eval(item.DataItem, "LocationID");
                if (dataBindingResult != null)
                {
                    litrl.Text = commonDataService.LocationGetById(Int32.Parse(dataBindingResult.ToString())).LocationName;
                }
            }
        }

When I try to filter Location column, it always brings back all records.

Cheers

Hey guys,

I'm redoing some code that was written by a previous coder. Basically, we have a poll, where we see the question (an optional question image) and 2-10 answers (with their optional images). There's also a ticker that ticks every 5 seconds. There's tons of ajax programmed in which causes the RadioButtonList and the button label (lblMessage) to refresh every 5 seconds. The images and the answer text are loaded into the list items of the RadioButtonList. So every 5 seconds or anytime a different radio button is selected, the images are repainted. Which makes the website really hard to look at more than a minute or two.

We do need the ajax for the radiobuttonlist due to the timer, unless there's another way to go around this. If the poll ends and the user selects a different answer, it will disable the radio buttons and notify that the poll is over. So I'm wondering if there's anyway to separate the images from the RadioButtonList, or another way to keep the images from repainting without losing functionality.



and here is the code behind



Thanks for your time!

I have multiple ajaxsettings where I want certain items to be updated, but it appears that items I haven't specified to be updated are being updated.

Here is an example:
var designSetting = new AjaxSetting(SelectDesignControl.ListControl.UniqueID);
designSetting.UpdatedControls.Add(new AjaxUpdatedControl(SelectProductControl.UniqueID, string.Empty));
designSetting.UpdatedControls.Add(new AjaxUpdatedControl(SelectInsertControl.UniqueID, string.Empty));
designSetting.UpdatedControls.Add(new AjaxUpdatedControl(HeroPanel.UniqueID, string.Empty));
designSetting.UpdatedControls.Add(new AjaxUpdatedControl(AddToBagControl.UniqueID, string.Empty));
ajaxManager.AjaxSettings.Add(designSetting);

var productSetting = new AjaxSetting(SelectProductControl.ListControl.UniqueID);
productSetting.UpdatedControls.Add(new AjaxUpdatedControl(SelectInsertControl.UniqueID, string.Empty));
productSetting.UpdatedControls.Add(new AjaxUpdatedControl(HeroPanel.UniqueID, string.Empty));
productSetting.UpdatedControls.Add(new AjaxUpdatedControl(AddToBagControl.UniqueID, string.Empty));
ajaxManager.AjaxSettings.Add(productSetting);

When selectproductcontrol.listcontrol is fired I don't want it to update itself, but it does. If i comment it out of the designsetting then it doesn't update. I need to have it included in that setting though.

I believe this is because the selectproductcontrol is wrapped in an updatecontrol since it is part of the previous setting. Is there anyway to make it so the selectproductcontrol is not updated when an event in it is fired?

Hi,
I have a RadGrid with some columns like edit, delete, other autogenerated columns. I want to add a listbox in editform dynamiclly.
Now I create dynamically a templatecolumn in radgrid that is not visible, then when I click to edit I see my ListBox and the other fields but there is a problem because if I click "Update" or "Cancel" the edit crash and you do not ecape from edit form pop-up.
Another problem is that when I go to edit form, the listbox column appear in the radgrid.

Thanks

I have an radtext box as a field in a list box. I am not sure how I go about getting that field to update. After the user fills in the field, what could I use to trigger the update?
