I was trying out my application as given in this example which is batch update using SqlDataSource in aspx code.
http://demos.telerik.com/aspnet-ajax/grid/examples/data-editing/batch-editing/defaultcs.aspx

But unfortunately, while updating/inserting, I get the database error that the values are null.
So how can I do the database updates in code

Count Number of Grouped Columns

In the GroupsChanging event of RadGrid, I want to count the number of columns that are currently grouped or just check to see if any grouping exists. Currently, I have it hiding the export to Excel/PDF buttons if it is a grouping action and unhiding if it is an ungrouping action. However, if there are more than one columns grouped, I still want to keep the export buttons hidden. If I do a check to see if there are any columns still grouped, I can continue to hide the export buttons. I can't seem to find any help on this. Thoughts?

Protected Sub gvAccounts_GroupsChanging(sender As Object, e As GridGroupsChangingEventArgs) Handles gvAccounts.GroupsChanging

If (e.Action = GridGroupsChangingAction.Group) Then

gvAccounts.AllowPaging = False

gvAccounts.MasterTableView.GetColumnSafe(e.Expression.GroupByFields(0).FieldName).Visible = False

gvAccounts.MasterTableView.CommandItemSettings.ShowExportToExcelButton = False

gvAccounts.MasterTableView.CommandItemSettings.ShowExportToPdfButton = False

ElseIf (e.Action = GridGroupsChangingAction.Ungroup) Then

IF ''add some code here to check if there are any grouped columns, if false then

gvAccounts.MasterTableView.CommandItemSettings.ShowExportToExcelButton = True

gvAccounts.MasterTableView.CommandItemSettings.ShowExportToPdfButton = True

End If

gvAccounts.AllowPaging = True

gvAccounts.MasterTableView.GetColumnSafe(e.Expression.GroupByFields(0).FieldName).Visible = True

End If

End Sub

RadTabStrip (elegant way to) prevent change tab on server side

How server code can prevent tab change in an scenario as linked sample?

sample: http://www.telerik.com/help/aspnet-ajax/tabstrip-multipage-integrate-with-tabstrip.html

I know than I can handle tabclick in this way:

protected void RadTabStrip1_handling_tabclick(object sender, EventArgs e)
{
RadTabStrip1.Tabs[0].Selected = true;
RadTabStrip1.Tabs[0].PageView.Selected = true;
}

But it seems a little dirty. I would like a kind of canceled radgrid event member for radtabstrip event:

protected void linkButton1_OnClick(object sender, EventArgs e){
e.canceled = true;
}

someone know a more elegant way to prevent change tab?

RadGrid Edit Mode Insert Next/New

Hi All,

The Users would like to be able to insert new records "back-to-back." Right now they click on "Add new record," fill in their data, click on "Insert" and have to repeat that process. They would like the addition of another button, next to "Insert," that allows for a new records to be added immediately after the current one. Essentially, the current record would be entered, the fields would be cleared and the RadGrid would remain in EditMode. Is this at all possible?

Thanks,
Mark

RadGrid virtual scrolling without pager using objectdatasource (no SQL!)

I need to create a grid that is filled from a custom objectdatasource. It should have no pager but when I scroll down (or up) it should dynamically load the appropriate data. I looked through all the examples but since they all use some sort of SQL I could not get them to work for me.

Are there any examples available with a custom objectdatasource?

Regards,
Rainer

Changing All Font Size in Grid

Hi All,

I am attempting to make the font size of all text in the RadGrid smaller. I have tried the following:

RadGrid.MasterTableView.Font.Size = FontUnit.XXSmall;

This appears to only affect the column headers. Does anyone have any suggestions?

Thanks,
Mark

GridDropDownColumn blank on postback

I have a GridDropDownColumn in RadGrid. I have added SelectedIndexChanged method on it in edit mode. Whenever this method is triggered, the column text becomes blank in the grid (for all rows except the one which is being edited).

I used the following in ItemCreated method:

rComboBox.AutoPostBack = true;
rComboBox.SelectedIndexChanged += MyComboBox_SelectedIndexChanged;

My GridDropDownColumn looks like:

<telerik:GridDropDownColumn DataField="MYDROPDOWNCOLUMN" DropDownControlType="RadComboBox"

HeaderText="Market Factor" ListTextField="MYDROPDOWNCOLUMN" ListValueField="MYDROPDOWNCOLUMN"

UniqueName="MYDROPDOWNCOLUMN" EnableEmptyListItem="true"

EmptyListItemText="--Choose an option--" EmptyListItemValue="">

</telerik:GridDropDownColumn>
