RadDropDownList OnSelectedIndexChanged doesn't hit event method

I added a RadDropDownList to my user control and added a OnSelectedIndexChanged but when I run the project and change the dropdown index, it doesn't hit the OnSelectedIndexChanged method.

<telerik:RadDropDownList ID="RadDropDownList1" runat="server" AutoPostBack="true" OnSelectedIndexChanged="RadDropDownList1_SelectedIndexChanged">

<Items>

<telerik:DropDownListItem Text="-- ALL --" Value="0" />

<telerik:DropDownListItem Text="Test 1" Value="1" />

<telerik:DropDownListItem Text="Test 2" Value="2" />

</Items>

</telerik:RadDropDownList>

protected void RadDropDownList1_SelectedIndexChanged(object sender, Telerik.Web.UI.DropDownListEventArgs e)

{

int x = -1;

x = e.Index;

}

I put a breakpoint on the first line of the SelectedIndexChanged method and it never gets in there.

Custom Add Task Popup

I decided to start a new thread instead of hijacking another, which i already did. Regardless, i am hoping Telerik can help with capturing the "Add Task" command and implementing my own custom popup. You have it for Edit Tasks, now is there a way for Add Tasks? This seems like a pretty common routine with other Telerik controls. I just dont see a way in your documentation and the limited client-side methods. Please help

[Solved] Expand Icon on Grid does not appear in custom theme

Hi.. I created a new theme (as you know)

When I apply the theme - the 'Expand' symbol/graph does not appear. See attachment. If i remove it I see the '>'.

Here's the generated CSS - how can I make the arrow appear or add my own image?

thx again!

.RadGrid_Flom .rgActiveRow td:not(.rgExpandCol) {
box-shadow: inset 0px 5px 5px -5px #676767, inset 0px -5px 5px -5px #676767;
}

.RadGrid_Flom .rgActiveRow td:first-child:not(.rgExpandCol),
.RadGrid_Flom GTT06222018 + td {
box-shadow: inset 0px 5px 5px -5px #676767, inset 0px -5px 5px -5px #676767, inset 5px 0px 5px -5px #676767;
}

.RadGrid_Flom .rgActiveRow td:not(.rgExpandCol):last-child {
box-shadow: inset 0px 5px 5px -5px #676767, inset 0px -5px 5px -5px #676767, inset -5px 0px 5px -5px #676767;

[Solved] items in pages

Based on RadioButtonList's selection, I determine the datasource of the RadGrid.

I have AutoPostBack to true for the RadioButtonList and do a Rebind in SelectedIndexChanged of RadioButton and it displays the data from different sources in the RadGrid just fine.

However, in the pager section, its not refreshing the number of items.

That is, say datasource A has 50 records and B has 100 records. Choosing between different radiobutton, it displays the records from A and B. But in pager section, it always shows number of items from datasource A.

RadGrid InputManager "Editor cannot be initialized for column"

Hi,

I have followed one of your examples from a while ago which has been working in my website for some time. I recently updated the Telerik AJAX controls to Q1-2013, but now the customer cannot add a record on one of the pages.

I have found that the code-behind uses a subroutine to apply an "InputSetting" to the editable control, very similar to this example:

http://www.telerik.com/help/aspnet-ajax/grid-linq-to-sql-manual-crud-operations.html

The way to prevent the "Editor cannot be initialized for column" error is to simply not use the "SetupInputManager" subroutine.

Obviously there was a breaking change made to the Telerik library at some point - what is the new way to replicate the functionality provided in the "SetupInputManager" subroutine (as shown in your examples)?

Thanks in advance!

[Solved] How can I get the DropDown List value from the Database

I have a problem That I need help with. I have a simple grid using all GridBoundColumns, except for 2 dropdown lists.

AllowAutoInsert and Updates are enabled so I do not do any code to show the value when I do an update. All of my fields that are using a GridBoundColumn show the proper values from the database. Except for the 2 drop downs. Both of DropDowns show no value at all.

Note the dropdowns do work and I can select a value, but the data from the database is not shown. Can anyone please tell me how or provide a link that shows how I can get these values to populate the drop downs?

I have attached a screen shot that shows the form in edit mode

Thanks

[Solved] Asp Radgrid, Get Cell values

Hello,

I have the following problem.

I have a Radgrid with cells default value=0

When i edit these cells for example i put the number 3 in the cell and click on save button

I get always "0" when i read the cell value instead of the Value 3 which i entered.

This is my code:

telerik:RadGrid ID="GridVK" runat="server"  Culture="de-DE" AutoGenerateColumns="False" MasterTableView-EditMode="InPlace">

<GroupingSettings CollapseAllTooltip="Collapse all groups"></GroupingSettings>

<ClientSettings>

<ClientEvents OnBatchEditClosed="batchEditClosed" />

</ClientSettings>

<MasterTableView EditMode="Batch" >

<BatchEditingSettings OpenEditingEvent="MouseUp" EditType="Cell" />

<RowIndicatorColumn Visible="False">

</RowIndicatorColumn>

<ExpandCollapseColumn Created="True">

</ExpandCollapseColumn>

<Columns>

<telerik:GridBoundColumn DataField="name" FilterControlAltText="Filter column1 column" HeaderText="Name" UniqueName="ColName">

</telerik:GridBoundColumn>

<telerik:GridNumericColumn DataField="Sells" DecimalDigits="2" FilterControlAltText="Filter column column" HeaderText="Sells" UniqueName="ColSells" EmptyDataText="0">

</telerik:GridNumericColumn>

</Columns>

</MasterTableView>

</telerik:RadGrid>

in VB:

For Each item As GridDataItem In GridVK.Items

vk = New Selldata

vk.vkname = item("colname").Text

vk.solljanuar = item("ColSells").Text

next

Why did i get always "0" instead the value i entered?

Sorry for my english.
