I have multiple radgrids on a single page. I have roughly 15 columns in one. Only 3 of the columns are set to display, however when running on my local machine only 2 of them display. In the developer tools of IE9 it shows it is being set as inline display: none. I have not set this and Have set it to display = true in my code with no luck. this is also happening on a two column grid where it is only displaying a single column in the grid. I am unsure of the issue and what is creating this. I have tried running IE in compatibility mode and have also tried different versions of IE.

I have to use IE 9 for this project.

RadGrid Code

Rad controls Performance Improvements

Hi Team,
Currently we are using Rad Controls for ASP.NET AJAX Q3 2010. While replacing the classic ASP.Net grid with Telerik Radgrid, we have noticed that the loading of telerik dll is taking around 6 - 7 seconds. Can anyone please confirm whether any performance issue have been reported on Rad Controls for ASP.NET AJAX Q3 2010.
Is there any improvements unloading the telerik dll in latest 2014 Q1 controls.

Thanks,
Suresh

Rad Editor Sometimes Runs Off The Page

We have the RadEditor inside a RadGrid. When the user adds a new record or edits one, the RadEditor applears to do the work.

Often, when someone firsts enters the site, goes to the page, and brings up the RadEditor, the RadEditor runs off the edge of the page expanding the RadGrid with it. The text area of the RadEditor is only one line high. See the attached picture (RadEditor_Error).

However, if the same person goes to another page, and comes back to the page, the RadEditor appears fine from then on. See attached picture (RadEditor_Good).

We have size settings on the Rad_Editor but this keeps happening.

Could someone please help.

Thank you,

Alex

RadDatePicker Filter in Grid not displaying correct date format

Hi Team,

I am using RadDatePicker to filter BoundColumn which gets the Date from the database in string format .

For getting Date from SQL Server , we are getting Date in format as 107 and Date string as "MMM dd,yyyy" .

For example we are getting date string from DB as "Jan 10,2014" . We are using RowFilter on date value selected from RadDatePicker.

But RadDatePicker is not displaying date in format needed that is "MMM dd,yyyy" .It is breaking at "," .

Please suggest way to change displaydateformat of RadDatePicker to "MMM dd,yyyy" to fix this issue.

I tried using

dtpicker.DateInput.DisplayDateFormat = "MMM dd,yyyy" ;

where dtpicker is ID of RadDatepicker .
It is not working , please suggest a way to fix this .

Regards,
-Dinesh Kotwani

RadComboBox LoadOnDemand PageMethod using multi column and attributes

Hi,

I am trying to implement a load on demand scenario for a RadComboBox but am struggling to get it to work with multi columns and attributes.

Here is the code for my RadComboBox

    
             <telerik:RadComboBox ID="ddlStudents"  
        
                 EnableViewState="false"

                        { 
        
                            return s.CombinedName.ToLower().Contains(context.Text.ToLower());

                        itemData.Attributes.Add("CombinedName", data[i].CombinedName); 
        
                        itemData.Value = data[i].StudentId; 
        
                        itemData.Attributes.Add("StudentStatus", data[i].StudentStatus); 
        
                        itemData.Attributes.Add("Year", data[i].StudentYear); 
        
                        result.Add(itemData); 
        
                    } 
        
                    comboData.Message = GetStatusMessage(endOffset, data.Count); 
        
                    comboData.Items = result.ToArray(); 
        
                    return comboData; 
        
                    }

The call to the PageMethod is working fine and the data is being populated in the RadComboBox, but the item template is ignored. All I am seeing is the returned Text property of the RadComboBoxItemData item. The documentation states that for attributes to work the way I am trying to use them, the RadComboBoxItem must call it's DataBind() method. Obviously this isn't happening on the web service request. Is there a way of doing this using LoadOnDemand and PageMethods/WebServices ?

Thanks

Validators?

Can you not use the required field validator or others with the search box? It will not let me.

Hide/Show Filtersbycolumn

Hello

I have a radgrid with AllowFilteringByColumn=true and a JS function that hides the filter when the grid is empty:

function Filter(masterTable) {
var dataItems = masterTable.get_dataItems();
if (dataItems.length == 0) { masterTable.hideFilterItem(); } else { masterTable.showFilterItem(); }
}

however when i perform a search and if that search returns no information, this script also hide the filters, and i dont want to hide after filter is applied(only when grid have no records).

There is a way to know if filters were used? im new to telerik.
Thanks in advance

Finding asp control in ItemTemplate in RadLightBox Client side

Hi
I am having problem with finding asp controls in the ItemTemplate in RadLightBox.
I have a RadComboBox and asp checkbox inside the RadLightBox ItemTemplate.
In my javascript I can find the RadComboBox, but cannot find the checkbox, it's getting null.
I also tried to find RadButton, it can find it, but how do I check it's checked or not from client side like asp checkbox.
But I still want to try to use asp checkbox so that css is consistent across our site.
Here is my code:
aspx:
<telerik:RadLightBox height="240" Width="890" ID="LightBox" Font-Size="Medium" runat="server" Modal="true" PreserveCurrentItemTemplates="true" style="z-index:99">
<ClientSettings >
<ClientEvents OnShowing="findControls" OnClosing="showHTMLScroll"/>
<AnimationSettings HideAnimation="Resize" NextAnimation="Fade" PrevAnimation="Fade" ShowAnimation="Resize" />
</ClientSettings>
<Items >
<telerik:RadLightBoxItem>
<ItemTemplate>
<div>
<div >

<asp:CheckBox ID="cb1" runat="server" Visible="true" />
<%--<telerik:RadButton ID="btnToggle" runat="server" ToggleType="CheckBox" ButtonType="LinkButton" >
<ToggleStates>
<telerik:RadButtonToggleState Text="Checked" PrimaryIconCssClass="rbToggleCheckboxChecked" />
<telerik:RadButtonToggleState Text="UnChecked" PrimaryIconCssClass="rbToggleCheckbox" />
</ToggleStates>
</telerik:RadButton>--%>
</div>
<div>
<telerik:RadComboBox runat="server" ID="RCB" Width="300" Height="300" Skin="MetroTouch"
EmptyMessage="-Please Select -" CssClass="right-field" Visible="true"
>
</telerik:RadComboBox>
<span> 
<asp:CustomValidator ID="cvl" runat="server" ValidationGroup="vgroup1" CssClass="error-label" ErrorMessage="Please select a reason"
ClientValidationFunction="cvlValidate" />
</span>
</div>
<div>
<span class="left-field left-label"> </span>
<asp:Button runat="server" CssClass="action-button" Text="Submit" value="Submit" ID="bnSubmit" CausesValidation="true" onclick="bnSubmitVoice_Click" ValidationGroup="vgroup1"/>
</div>
</div>
</ItemTemplate>
</telerik:RadLightBoxItem>
</Items>
</telerik:RadLightBox>

javascript:

function findControls() {
var cb = $find('<%= ((CheckBox)LightBoxReasonVoice.FindControl("cb1")).ClientID %>');;
var rcb = $find('<%= ((RadComboBox)LightBoxReasonVoice.FindControl("RCB")).ClientID %>');
alert("cb.checked");

}
