[Solved] CellBeginEdit e.rowindex is incorrect

I need to interrogate a cell on the row being edited to determine if editing is allowed. The cell I'm trying to retrieve is a hidden column, not the one the user is trying to edit. When I look at the value of e.rowindex it doesn't match the row being edited. The grid is a hierarchy view. The value of e.rowindex seems to be associated with the rows being displayed at that hierarchy level.

How can I get the row being edited?

I switched over to the latest release and this fixed the problem.

2010 Q3: DropDownList RadListDataItem Binding Bug?

Hi!

I was using Q2, 2 dropdownlists with prices binded to it and it worked fine:

RadListDataItem rcbi0 = new RadListDataItem("ANY");

RadListDataItem rcbi1 = new RadListDataItem("1");

RadListDataItem rcbi2 = new RadListDataItem("10");

RadListDataItem rcbi3 = new RadListDataItem("15");

RadListDataItem rcbi4 = new RadListDataItem("20");

RadListDataItem rcbi5 = new RadListDataItem("25");

RadListDataItem rcbi6 = new RadListDataItem("30");

RadListDataItem rcbi7 = new RadListDataItem("40");

radDropDownListPriceMin.Items.AddRange(new[]{ rcbi0, rcbi1, rcbi2, rcbi3, rcbi4, rcbi5, rcbi6, rcbi7});

radDropDownListPriceMin.SelectedIndex = 0;

radDropDownListPriceMax.Items.AddRange(new[]{rcbi0, rcbi1, rcbi2, rcbi3, rcbi4, rcbi5, rcbi6, rcbi7});

radDropDownListPriceMax.SelectedIndex = 0;

Now , the same above code but with Q3, binds the RadListDataItems to radDropDownListPriceMax BUT

radDropDownListPriceMin is empty!



This code works fine in Q3:

string[] pricesList = new string[7];

pricesList[0] = "ANY";

pricesList[1] = "1";

pricesList[2] = "10";

pricesList[3] = "15";

pricesList[4] = "20";

pricesList[5] = "25";

pricesList[6] = "30";

radDropDownListPriceMin.Items.AddRange(pricesList);

radDropDownListPriceMin.SelectedIndex = 0;

radDropDownListPriceMax.Items.AddRange(pricesList);

radDropDownListPriceMax.SelectedIndex = 0;

How come?

[Solved] CellValueChanged event not fired

Hello everybody.

I'm having the current problem with RadGridView (using Q2 2010):

The GUI has the following structure: RadRibbonForm contains SplitPlanel contains UserControl contains RadGridView.
Now, the GridView is bound to a List of objects. I'm using a CheckBox column for one property.

Now, I click into the checkbox cell, changing the ToggleState of the checkbox, but do not leave the cell by clicking on a different row. I do some necessary logic in the GridView_CellValueChanged event handler.
The I click the Save-Button which is located on the RibbonForms QuickAccessBar, but the data is not correctly saved.

After debugging, I realized that the CellValueChanged is neither triggered, when I click into the cell, nor when I click the Save-Button (would have thought so, because the cell should lose focus, accepting my data change).
If I click into a different row, my change to the combobox is accepted and correctly saved.

What can I do to solve this problem? Is there a method to make the grid change its cell values without leaving the edited row?

Thanks for any help

[Solved] Select some row on filter changing

Hi,
I'm using the RadGridView in which I always wanted to keep a row selected, in the case when the filter expression is changed, all the rows are unselected. I presume that the filtering row is selected at that time.
So I subscribed the FilterChanged event, and at which I select the first row. The problem I'm facing is that, the filter changed event is generated for every character I type, and the focus switches to the first row.

Please help me out for finding a solution. Thanks.

[Solved] bind image to a databind combobox

Hello,

I am new at this as I am trying to learn and get comfortable with Telerik. I have a winform app with 2 combo boxes, which are bind from a dataset/datatable. And I would like some sample code on how to bind different images to all each item in my combo box 1 and combo box 2.

After that I would like to code for the selected_index changed of the combo box 1. I would like to re-bind the data of the combo box 2 base on the selection on combo box 1.

I can do all of that in the normal combo box where I manually typed in all the items to the combo box and then uses the RadListDataItem Collection Editor to add in the images....but I want to do it with code as my combo box 2 changes base on the selection of combo box 1.

Thanks.
