Hello,

I have a radgrid which is bound with records from one tables. I want to bind radGantt chart in expanded grid row. Is it possible to display Gantt chart inside grid?

I have two tables, e.g. A & B

I am bindding A to grid, and I want to show it's relevant tasks with statuses in ganttchart when expand grid row. I don't want any updates on ganttchart. It is just a view purpose. Also I am not caring for predessor and successors.

Please let me know if such requirement is possible or not. If not then suggest how can I implement this functionality using any other controls.

Hello,

The bug can best be described as the following:

When setting a radgrid datasource with an IEnumerable, filterexpressions behave not as expected.

Reproduce:

Create a radgrid with EnableLinqexpressions set to true, and set its datasource to an IEnumerable. Set a filter on a column. Check the filterexpression that is being generated. Notice the filterexpressions is NOT a valid linqexpression, but has the following format: "([CustomerID] LIKE '%ALFKI%')";

Now set the datasource to a list instead of an IEnumerable. Notice that suddenly the filterexpressions that is generated is different.

See also your Filterexpression documentation

Issue:

I have a requirement where i have to set an initial filter in a grid when opening the page. But we also have export buttons on that page that use the grids filterexpression to filter a dataset for the export. This no longer worked because the filterexpression was no longer a valid linq expression. In my opinion this behavior is not very intuitive, and i could not find any documentation about it.

Regards,

Johan

I am dynamically creating an ajaxified RadGrid in an asp:UpdatePanel in a user control.

The RadGrid is created in Page_Init,and the MasterTableView.CommandItemSettings.ShowExportToExcelButton set true;

The RadGrid is added to the RadAjaxManagerProxy AjaxSettings in Page_Load, in if (!Page.IsPostBack).

My problem is that after postback, the export button is not set to trigger a postback (it's not excluded from Ajax). I gather it is excluded automatically on the original page load when the RadGrid is added to the AjaxSettings, but it doesn't happen after a ajax update to the RadGrid (sorting, or filtering, for example).

I read this article, but I can't resolve my problem: Export from Ajaxified Grid

If I inspect the button in the browser before and after an ajax update this is what I see:

BEFORE:
<input name="ctl00$MainContent$ucSystems$rgSystems$ctl00$ctl02$ctl00$ExportToExcelButton" title="Export to Excel" class="rgExpXLS" id="ctl00_MainContent_ucSystems_rgSystems_ctl00_ctl02_ctl00_ExportToExcelButton" onclick="javascript:__doPostBack('ctl00$MainContent$ucSystems$rgSystems$ctl00$ctl02$ctl00$ExportToExcelButton','')" type="button" value=" ">

AFTER:

<input
name="ctl00$MainContent$ucSystems$rgSystems$ctl00$ctl02$ctl00$ExportToExcelButton"
title="Export to Excel" class="rgExpXLS" id="ctl00_MainContent_ucSystems_rgSystems_ctl00_ctl02_ctl00_ExportToExcelButton"
type="submit" value=" ">

How can I get the postback on the ExportToExcelButton after an ajax update to the RadGrid?

Hi,
Wonder if someone could give me a hand with a problem.  I have a radgrid with two columns.  One column is a raddropdownlist with three static items.  The user changes the dropdownlist values as required and then clicks the SAVE button which invokes a code behind function.

At this point I iterate through the rows, getting the values of the two columns to then save manually in my database.

Whilst I can get the first databound column (menuname), what ever I do the raddropdownlist returns nothing.

I've tried various options including findcontrol, mastertable getdatakeyvalues, tablecells but everything returns nothing.

                   <telerik:RadGrid ID="RadGrid1" runat="server" AutoGenerateColumns="False">
                        <GroupingSettings CollapseAllTooltip="Collapse all groups"></GroupingSettings>
                        <ClientSettings>

                        </ClientSettings>
                        <MasterTableView EditMode="Batch">
                            <Columns>
                                <telerik:GridBoundColumn DataField="menuname" UniqueName="menuname" HeaderText="Plugin" ReadOnly="True">

                                    <ItemTemplate>
                                        <%# Eval("pluginperm") %>
                                    </ItemTemplate>
                                    <EditItemTemplate>

                            </Columns>
                        </MasterTableView>
                    </telerik:RadGrid>

I know "b = item("pluginperm").ToString" won't work - I've just put it in for completeness.

... in the code behind function 

          For Each item As GridDataItem In RadGrid1.Items
              Dim a As String
              Dim b As String
              a = item("menuname").Text
              b = item("pluginperm").ToString

          Next

I know "b = item("pluginperm").ToString" won't work - I've just put it in for completeness.

Any help would be really appreciated.

I have a grid that I want to make a specific cell only to be in edit mode and never go in view mode

RadGridControl.MasterTableView.BatchEditingSettings.EditType = GridBatchEditingType.Cell; (using the batcheediting with cell editing)

https://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

Like in this demo, I have a checkbox that I don't want to be shown in view mode, just in edit mode. Made a thing that the checkbox will work without clicking it twice(once to select the column and one to select the checkbox), it works with already saved items, but when i insert a new row the view mode doesn't display the checkbox, but the editing mode displays it.... I can't manage to show it in the view mode, so the only think is when I insert a new row to place it automatically in edit mode, can I even do this(without generating a lot of errors)?

I have a RadGrid in batch edit mode, cell edit.  I'm using the events 'OnBatchEditOpened' to manipulate some of the UI before the user gets to see/use it and then 'BatchEditCellValueChanged' to run further logic.

I have a pair of cells in the grid, in column X, that need to be the opposite of each other's selections in the rad comboBox I'm using in the editor.  If one cell has optionA selected in row A then the other cell needs to show optionB in row B.  The issue I'm running into is that to change cell values I have been using this method:

    batchManager.changeCellValue(cellToChange, valueToUse).

This works fine...normally when I'm updating values in some OTHER grid.  But when I run this logic from the 'BatchEditCellValueChanged' method of the SAME GRID then the grid gets a bit wonky.  I already have code to avoid recursive looping.  The problem is that the grid has a set of functions that are fired in a set sequence, like opening, opened, changing, changed, closing, closed, etc.  When you cause that data flow to step INTO itself before the first is finished... it winds up leaving the edit control visible in the starting cell.

So - CellA opens in editor, I select the radComboBox option A and tab out of the cell.  This causes Telerik's event chain to start firing... it gets to 'BatchEditCellValueChanged' and runs my code.  My code then tell the SAME grid to update CellB in the other row... and that starts the grid's event chain to START OVER... before CellA's 'value changed' event is finished.  I think this is what is causing the logic issues and is making the editor, i.e. the radComboBox in CellA, to remain visible even after I exit the cell.

So - all that being said.  What is the 'correct' way to change cellB's in row B when cellA's value changes in rowA of the same batch edit grid?

I am attempting to place a confirm delete prompt message on a RadButton in a GridTemplateColumn.  Depending on the browser, I am getting mixed results, none of which are acceptable.

In Edge and Chrome, Pressing the delete button pops the message up, but pressing Ok or Cancel will pop the message up second time immedately, and pressing Ok or Cancel on the second message will perform the action desired (Cancel will close message and do nothing, Ok will fire DeleteCommand on server side)

In IE11, pressing the Ok or Cancel will show the confirm message only once.  Ok will run the DeleteCommand routine as expected.  However, Cancel will ignore the cancel and ALSO run the DeleteCommand routine.  

My guess is whatever is causing the issue to show a double-message in Edge or Chrome is being ignored in IE and it just fires the delete command regardless of what button was pressed on the confirm message.

Here are some code snippets:
