Selecting detail table rows when selecting master table row (Client side)

Hello all

I have the following issue, I searched the demos and the forum and I didn't find what I want:

I have a grid with master table, and this grid have a detailed table which bounded on demand using DetailTableDataBind, ie when the user clicks expand button the detail table appears filled with data.

Also I have GridClientSelectColumn for the master and the detail (all the columns are coded in ASPX page NOT AutoGenerated)

    
            <telerik:GridClientSelectColumn UniqueName="selColumn"> 
        
            </telerik:GridClientSelectColumn>

what I need is when the user clicks the Select checkbox for the master table, ALL rows in the detail table must be selected, and when the user clears (deselect) the checkbox of the master table, ALL the rows in the detail table must be cleared. Of course this must happen in client side functions or APIs (JavaScript).

Please help me ASAP..

Thanks in advance

Regards..

Problem Updating values in grid

Hello,

I'm designing a grid editing the individual records "InSite", using a Edit/Update-Cancel button, after push Edit Button, the row becames editable and I change some values, but when I push "Update" the labels are still showing the original values, they don't change at all.
This is my simplest code:

.aspx

    
            <telerik:RadGrid runat="server"  ID="RadGrid1" 
        
                    OnNeedDataSource="RadGrid1_NeedDataSource" 
        
                    AutoGenerateColumns="false" 
        
                    AllowAutomaticUpdates="false" 
        
                     > 
        
                    <MasterTableView EditMode="InPlace"> 
        
                        <Columns> 
        
                            <telerik:GridBoundColumn DataField="Id"/> 
        
                            <telerik:GridBoundColumn DataField="Name"/> 
        
                            <telerik:GridEditCommandColumn />

                    </MasterTableView> 
        
                </telerik:RadGrid>

.aspx.cs

    
            class Entity{ 
        
                    private int _id;

Control still uses EmbeddedCSS even prohibted

Hello,

I created my first skin for RadUpload (Q2 2009), and i put them in my App_Theme folder as follow:

App_Themes
- Green
- - Upload
- - - logo.gif
- - - ruProgress.gif
- - - ruSprite.png
- - Upload.css
- - Upload.Grn.css
and set the properties of the control in the page to (besides setting the theme of the page)

    
            <telerik:RadUpload ID="radUploader" Localization-Select="Select File" runat="server" Skin="Grn" EnableEmbeddedSkins="false"  EnableEmbeddedBaseStylesheet="false"  EnableFileInputSkinning="true" ControlObjectsVisibility="none" 
        
                                            ReadOnlyFileInputs="true" MaxFileInputsCount="5" > 
        
                                            <Localization Select="Select File" /> 
        
            </telerik:RadUpload>

I increased the width of the font of the button and hence the width of the button too,
when i ran the page, i got the font bigger and the sprite image is used properly, but the problem with the width, when i traced the style used i found that my theme styles were included but they were overridden by the embedded styles!!!! even that i disabled them.

can you help please?

P.S. i cannot remove the Telerik_StyleSheet links, since there are other styles for other telerik controls that i still need them.
P.S2 if needed I can attach the CSS files and a screen shot.

Cannot find Column error

I have two radgrids on a form with autogeneratecolumns turned off viewstate turned on I am also using the needdatasource event. The grid is being populated in the background via a datatable that is loaded from another method. The data is loaded based on what value the user chooses from a drop down list. When the value is selected the datatables are then populated and the grid is rebound. I am calling the RadGrid.Rebind() method from within the drop down's selecteditemchanged method.

When a user tries to filter using the filter control or they try to sort a column they receive an error stating that "Cannot find column" This error occurs for every column and in both grid boxes I have searched everywhere and cannot find a solution to this. I have included some code snippets (both grids are pretty much exactly the same in code so I only included one grid) and the error stack trace. I have double checked to make sure that the datasource column names match the sortexpression and the DataKeyField for each column. I made sure not to call Databind from the Page_load leaving the grid binding up to needdatasource. I am thinking that it might be caused by me calling rebind from the dropdown's selectedindex change method but how can I force the grids to rebind without calling the ReBind method since the needdatasource is not being triggered on postback.

Cannot find column Firstname.

Filtering non mapped fields

Hi there.

I added a new field to my entity not mapped to Database, when i displayed the field using RadGrid, i have no problem, i assigned the value and is displayed sucessfully, the problem is when i try to filter the value..., I'm created a combo box into the filter, but when the selectindex changed:

<telerik:RadScriptBlock ID="RadScriptBlock3" runat="server">

function StatusIndexChanged(sender,args) {

var tableView=$find("<%# ((GridItem)Container).OwnerTableView.ClientID %>");

tableView.filter(

"NivelAdecuacion",args.get_item().get_value(),"EqualTo");

}

</script>

</telerik:RadScriptBlock>

An error is throw: The member XXX.NivelAdecuacion not admit SQL Conversion.

I supose that is due to the field is not mapped into Database table, is an added field, can anybody tell me how to solve this, please...

Thanks in advance

Displaying Only the Dropdown Toggle

Is there a way to hide the input area of the combbox box until the user clicks the dropdown toggle button?

I'm setting the DropDownWidth="70px" which is fine, but I only want the dropdown button to show when the control is not in use.

Thanks,

Ken
