I have a RadDropDownColumn and I would like to fill it using DataSoruceID='<%# GetCompany() %>' excuse me if I make a mistake using this way, just I need to know if this way is possible..otherwise how can I fix it?

Regards

I have an issue validating GridDropDownList - it does not validate as other controls do. I have created a custom validator in the code behind but it does not fire when no value selected.

Thank you,

Steve O...

Hey guys,
I've just purchased the full licence of ASP.NET AJAX yesterday.
I want to have a grid with this layout for each row:
<ul>
       <li class="hover">
        <span class="result-check">
         <input type="checkbox" name="test" value="more-sub" />
        </span>
        <span class="result-img">
         <img src="#" />
        </span>
        <span class="result-detail">
         <span class="info-1">
          <label>Unit</label><span class="value"><%# Eval("Unit")%></span>
          <label>Name</label><span class="value"><%# Eval("Name")%></span>
          <label>Type</label><span class="value"><%# Eval("Type")%></span>
         </span>
         <span class="info-1">
          <label>Area m²</label><span class="value"><%# Eval("Area")%></span>
          <label>Divisible area</label><span class="value"><%# Eval("DArea")%></span>
         </span>
         <span class="info-1">
          <label>Rent m²</label><span class="value"><%# Eval("RArea")%></span>
          <label>Rent p.a</label><span class="value"><%# Eval("RPA")%></span>
         </span>
         <span class="hover-info">
          <span><a href="#" class="view">View</a></span>
          <a href="#">Edit</a>
          <a href="#">Email</a>
          <a href="#">Print</a> |
          <a href="#">Add an enquiry</a> |
          <a href="#">Create note</a>
         </span>
        </span>
        <span class="result-medium">
         <span>M</span>
        </span>
       </li>
</ui>

My datasource is a Generic List. When I use Itemtemplate, my grid stays empty.
I would be so thankful if you can reply ASAP.

Cheers

Hi All,

I am using the RadGrid and have added a GridBinaryImageColumn. The ROW gets bigger when an image is in the record (rows where there are NO image data, are lean, this is just because I defined width and height manually in order to see if something is happening once there is an image in the database).

However, although there is a larger space in the column I cannot see any picture. The database table itself has an image field. I tried to read binary date through writing a memory stream to a bitmap and this worked fine.

Working with the BinaryImageColumn doesnt show any picture. Please find below the code.

I have set HeaderText and DataField to the name of the database table field, which is 'Signature'.

I have set DataType to System.Byte

  <Columns>
        <telerik:GridBoundColumn DataField="OrderNumber" DataType="System.Int32"
            HeaderText="OrderNumber" SortExpression="OrderNumber"
            UniqueName="OrderNumber">
        </telerik:GridBoundColumn>
        <telerik:GridBoundColumn DataField="ParcelNumber" HeaderText="ParcelNumber"
            SortExpression="Parcelnumber" UniqueName="ParcelNumber">
        </telerik:GridBoundColumn>
        <telerik:GridBoundColumn DataField="DeliveryTime"
            DataType="System.DateTime" HeaderText="DeliveryTime"
            SortExpression="DeliveryTime" UniqueName="DeliveryTime">
        </telerik:GridBoundColumn>
        <telerik:GridBinaryImageColumn AlternateText="" DataField="Signature"
            HeaderText="Signature" ImageAlign="Left" ImageHeight="100px"
            ImageWidth="200px" UniqueName="Signature">
        </telerik:GridBinaryImageColumn>
        <telerik:GridCheckBoxColumn DataField="Retoure" DataType="System.Boolean"
            HeaderText="Retoure" SortExpression="Retoure" UniqueName="Retoure">
        </telerik:GridCheckBoxColumn>
    </Columns>

Hi there,

Happy new year for all!!!
How to use a radiobutton inside gridTemplateColumn as editcommand button?
When you check a radiobutton, the corresponding row should get changed to edit mode.

Thanks in advance,

Toby

I have followed the example here to the letter:

http://www.telerik.com/help/aspnet-ajax/radgrid-filter-template.html

I have used the code-behind method since I am not using an EntityDataSource. However, it just doesn't work. After selecting a different item from the combobox it goes through the code to set the filter but then the combobox just gets reset to it's original value and nothing is filtered.

Here is my grid:

And here is the event handler:


What gives? It seems like the filtering is a great feature but once you start getting into a complicated design (multiple master pages, user controls etc. all of the functionality is broken. I wouldn't even be trying to use the FilterTemplate if the normal filters worked on this page but they don't. No filteroptions are even displayed upon clicking the filter image.

Filtering on this grid is needed and I do not want to have to re-write my query so that I can pass in all of the filter criteria and then do all the filtering manually, that kind of defeats the purpose of using your controls.

Any help to get this resolved is greatly appreciated.

Thanks!

I have some hidden columns and some external comboboxes that controls the filter mechanism in the grid.
I filter using the hidden columns (I don't want to show these columns in the grid).
If I set allowfilteringbyColumn = "true" then the filter row shows up. I don't want to show the filter row but still aloowcolumnfiltering on my grid. Without that feature the grid loses its filterexpression and I find it hard and messy to apply multple filters.

Can you show me how to hide the filter row. I use multiple instances of grid throughout my application, so I don't want to change the grid css.

Thanks,

I created a simple page with a button inside a RadAjaxPanel and several labels inside their own RadAjaxPanels.  I set the update mode on each RadAjaxPanel to Always using the AjaxSettingCreating event.  The button click event sets the text property of each label to the current DateTime.  In theory, when I click the button, every label should update to the current DateTime.  However, none of the labels update. 

I also put two ASP.NET UpdatePanels on the page with labels in them and their update modes set to Always.  They do update correctly, but not the RadAjaxPanels.

What am I missing?

Hello,

I'm trying to change the "Grid / Using Server-side API" demo to have the drop-down list pull data from a different data table or data source.

To illustrate the scenario, here is a theoretical example:

1. Lets say I have a stored proc called SP1 returning a list of customers who bought cars. The proc returns customer_id, customer_name and car_make_id.
2. Lets say I have another stored proc called SP2 that returns a list of the car makes (make_id and make_name).
3. Lets say I'm implementing a structure very similar to the "Grid / Using Server-side API" demo.

How could I arrange the bindings if I want the grid to show customer data based on the data from SP1 displaying a customer name (just a textbox - easy stuff) and a car make (a drop-down list with a list of all makes returned by SP2, with the customer's car make selected)?

To clarify the situation a little bit:

The demo is located here: http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/extractvalues/defaultcs.aspx
It has a drop-down box that is bound to the same datasource as everything else and therefore would not display a distinct list of items... or car makes in the example I've made up above. Instead it would just show a non-unique list of all make IDs associated with the customers so far (and would not show makes that exist in the Make database table, but haven't been yet associated with the customers).


Any help would be truly appreciated.

Thank you!
