Finding a control in the RadGridView.EditFormSettings.FormTemplate

I have a page with a RadGrid on it. In that RadGrid I'm using <EditFormSettings EditFormType="Template"> to handle the editing of the data. In that FormTemplate I have a FileUpload control where I'm allowing users to upload a file. I planned on handling the file upload in a seperate function. Problem is trying to get to the FileUpload control. Can someone help me? Code sample below:

<telerik:RadGrid

ID="rgvwUserList"

runat="server"

AllowAutomaticDeletes="True"

AllowAutomaticInserts="True"

AllowAutomaticUpdates="True"

AllowFilteringByColumn="True"

AllowPaging="True"

AllowSorting="True"

AutoGenerateColumns="False"

CellSpacing="0"

DataSourceID="sdsUserList"

EnableLinqExpressions="False"

GridLines="None"

PageSize="20"

ShowGroupPanel="True"

Width="900px">

<ClientSettings AllowDragToGroup="True"/>

<MasterTableView

AutoGenerateColumns="False"

CommandItemDisplay="None"

DataKeyNames="StaffID"

DataSourceID="sdsUserList"

EditMode="EditForms"

HorizontalAlign="NotSet"

Width="100%">

<Columns>

<telerik:GridEditCommandColumn ButtonType="ImageButton" HeaderText="Edit" ItemStyle-HorizontalAlign="Center" UniqueName="EditCommandColumn">

<ItemStyle CssClass="MyImageButton" Wrap="False" />

</telerik:GridEditCommandColumn>

<telerik:GridTemplateColumn AllowFiltering="False">

<HeaderStyle HorizontalAlign="Center"/>

<HeaderTemplate>Photo</HeaderTemplate>

<ItemStyle HorizontalAlign="Center"/>

<ItemTemplate>

<asp:Image ID="imgPhoto" runat="server" ImageUrl='<%#EVAL("PhotoPath") %>' Width="50"/>

</ItemTemplate>

</telerik:GridTemplateColumn>

<telerik:GridBoundColumn DataField="DisplayName" FilterControlAltText="Filter DisplayName column" HeaderText="DisplayName" ItemStyle-Width="20%" ReadOnly="True" SortExpression="LastName" UniqueName="DisplayName"/>

</Columns>

<EditFormSettings EditFormType="Template">

<FormTemplate>

<div align="center">

<asp:FileUpload ID="fuPhotoPath" runat="server" SkinID="FileUpload" Width="290"/>

<asp:Button ID="btnAddPhoto" runat="server" CommandArgument='<%#Bind("StaffID")%>' OnCommand="UploadPhoto" SkinID="ButtonLittle" Text="Add"/>

</div>

</FormTemplate>

</EditFormSettings>

</MasterTableView>

</telerik:RadGrid>

RadTreeView node text highlight/selection

I'm trying to figure out how to get the treeview to allow clean text selection of the text in the nodes and items inside node templates (labels etc). I have searched all over for a solution to this and it seems to be that different versions of RadTreeView allow this while others do not.

For example here, you can highlight the text of the nodes and smaller parts of the text fine:
http://mono.telerik.com/TreeView/Examples/Functionality/SingleExpandPath/DefaultCS.aspx

Yet in this newer example, you can't:
http://demos.telerik.com/aspnet-ajax/treeview/examples/functionality/expandanimation/defaultcs.aspx

You can sometimes select the text if you start clicking far outside the node and drag, but there is no way to select sub parts of the node text.

If anyone has any idea how to get text selection to work properly with TreeView please help!

findItemByValue not working using concatenated string as parameter

Hi,

I'm sure this is something silly on my part, but I can't spot it.

The following code works:

var x = 'text';

var y = 'Red';

var selectedColorButtonValue = String(x + y);

var selectedColorButton = toolBar.findItemByValue(selectedColorButtonValue);

Now, since the actual value of y is dynamic and only known at run time, I have this code:

var selectedColorButtonValue = getColorButtonValue(fontColor); // Returns 'Red' for this demo

selectedColorButtonValue = String('text' + selectedColorButtonValue);

var selectedColorButton = toolBar.findItemByValue(selectedColorButtonValue);

The above does NOT work. The toolbarbutton that I'm trying to find is not found!

The toolbarbutton in question is one of several items in a RadToolBarSplitButton.

I have written to the console, and the value of selectedColorButtonValue appears fine.

Can anyone spot what I'm doing wrong.

Thanks

Jim

pass parameters to user control used for edit mode

Hello

I'm having problem passing parameters to user control used in edit mode of radgrid

I Have a RadGrid with some users data. I use a custom user control for FormTemplate.

The user control has it's own logic implemented to edit user data and takes one parameter "id_user". (It has public String id_user with get and set method defined in codebehind)

I tried to pass this parameter to UserControl as seen in code below, but it doesnt work. when i pass this parameter to label it shows. User control also works fine if I pass static parameter (example: id_user="2" ).

What is the right way to pass parameters to UC?

    
            <EditFormSettings EditFormType="Template"> 
        
               <FormTemplate> 
        
                   <asp:Label ID="Label4" runat="server" Text='<%# Bind("id") %>'></asp:Label> 
        
                   <uc1:edit_user ID="edit_user1" runat="server" id_user='<%# Bind("id") %>' />    
        
               </FormTemplate> 
        
               <EditColumn CurrentFilterFunction="NoFilter" FilterListOptions="VaryByDataType" 
        
                           uniquename="EditCommandColumn"> 
        
                </EditColumn> 
        
            </EditFormSettings>

I'm would also like to know how to pass parameters when attachig UserControls like this:

    
             <EditFormSettings EditFormType="WebUserControl" UserControlName="edit_user.ascx">

Thank you

setting colspan="2" corrupts grid columns when HScrolling

I have a dynamically generated grid where the first 4 rows are basically headers. "Project Name", "Customer Name", "division Name", "Sector Name"

For each project we have 2 columns. "Plan" and "Assign".

The 4 headers I listed should span the plan and assign columns. See the attached screen shot "Report Before Scrolling (everything looks good).png" to see what the desired output should be.

I used this thread as a starting point on how to make text in one row span 2 columns for a dynamically generated grid:

http://www.telerik.com/support/code-library/span-cells-in-grid-over-multiple-positions

My guess is that the part where you try to track the previousIndex compared to the current index is where I have issues.

When the report is first rendered to the screen it looks correct. Once you use the horizontal scroll the colspan values for the columns start to change. To see the HTML example of this I've included 2 screen shots. One called "HTML Before Scrolling - Colspan values look correct.png" and one called "HTML after scrolling -Colspan values have changed.png".

Here is the OnPreRender code where I set the colspan and very feebly attempt to manage the indeces of the items (read help!):

protected void radGrid1_OnPreRender(object sender, EventArgs e)

{

var headerRows = HeaderRows;

if (headerRows == null) return;

foreach (var row in headerRows)

{

var currentProjectID = row["projectID"].ToString();

var currentPlanColumnName = "Plan" + "_" + currentProjectID;

var currentAssignColumnName = "Assign" + "_" + currentProjectID;

foreach (GridDataItem dataItem in radGrid1.MasterTableView.Items)

{

dataItem[currentPlanColumnName].ColumnSpan = 2;

dataItem[currentAssignColumnName].Visible = false;

int previousItemIndex = dataItem.ItemIndex - 1;

if (previousItemIndex >= 0)

{

if (dataItem["Employees"].Text == dataItem.OwnerTableView.Items[previousItemIndex]["Employees"].Text)

{

dataItem.OwnerTableView.Items[previousItemIndex]["Employees"].RowSpan = 2;

dataItem["Employees"].Visible = false;

}

As I stated above the code in the OnPreRender where it compares the dataItem text to the previousItemIndex's text is where I'm probably causing the issue??

Any help is greatly appreciated.

Thank you :)

RadCombox Custom Text being Saved even if Allowcustomtext ="false"

Hi Guys,

I have a strange issue where the radcombobox allows the user to enter text and search data, also this data which he entered is allowed to save.

<telerik:radcombobox id="rdChangeOwner" skin="Web20" cssclass="RadComboBoxDropDownrcbScroll"
dropdowncssclass="RadComboBoxDropDownrcbScroll" runat="server" font-names="calibri"
font-size="11pt" width="230px" allowcustomtext="false" height="180px" enableloadondemand="True"
showmoreresultsbox="true" enablevirtualscrolling="true" emptymessage="Please Select..."
radcomboboximageposition="Right" zindex="10000002" onitemsrequested="ddlChangeOwnerItemsRequested"
causesvalidation="true" highlighttemplateditems="true" onclientblur="rdChangeOwnerBlur">
</telerik:radcombobox>

Initial Value of DropDown is "Asif Mohammed"

Looking for a Employee in picker and entered Asif

Didn’t not select the populated value(Asif Mohammed), just left the entered text as "Asif".

Asif is not there in the list, but "Asif Mohammed" is available, but it allowed me to save Asif into DB and hence got me error because internally it was not able to resolve.

Please help in getting a solution for this Issue.

Thanks and Regards,

Mohammed Asif Mtext
