Hi All,

here is what I am trying to achieve;

While my Telerik data form is in InsertNewItem mode, I need to use user's data entries in any of the RadTextBox as they enter it, before they click on the "Insert" button. I need to be able to extract that data entry once they move focus away from that TextBox so that I can use it to run data query and fill other textboxes in the same InsertItem form template. Later the user will have the ability to click on Insert to add that new record to the SqlDataSource already linked to the Telerik DataForm.

your help is highly appreciated!

Hi, I am new to Kendo UI and especially with its Grid.

Is there a way to emphasise the editable field of a Kendo Grid?

Thank you very much.

I have a RadGrid with a customized GridDrownColumn, everything based on this http://docs.telerik.com/devtools/aspnet-ajax/controls/grid/how-to/customize-griddropdowncolumn The dropdown is working ok, i've had problems cause in gridViewMode the column was empty, however i manage to handle this.

Now the only problem es when the record is in EditMode, the selected value in the combo is always the first element of the list, no matter wich value is selected

protected void GridSCG_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem) //This is how i show the value in view mode
            {
                GridDataItem item = (GridDataItem)e.Item;
                SCG_DATOS_ADUANA_238 row = (SCG_DATOS_ADUANA_238)e.Item.DataItem;
                item["DTA_TRAFICO"].Text = row.DTA_TRAFICO;
            }
            if (e.Item is GridEditableItem && (e.Item as GridEditableItem).IsInEditMode)
            {
                GridEditableItem editedItem = e.Item as GridEditableItem;
                GridEditManager editMan = editedItem.EditManager;

                GridDropDownListColumnEditor editor = editMan.GetColumnEditor("DTA_TRAFICO") as GridDropDownListColumnEditor;
                editor.DataSource = new DropDownListItem[] { new DropDownListItem("I", "I"), new DropDownListItem("E", "E") };
                editor.DataTextField = "Text";
                editor.DataValueField = "Value";
                editor.DataBind();

                SCG_DATOS_ADUANA_238 row = (SCG_DATOS_ADUANA_238)editedItem.DataItem;
                if (row.DTA_TRAFICO != "")
                {
                    if (row.DTA_TRAFICO == "I")
                        editor.DropDownListControl.SelectedValue = "I";
                    else
                        editor.DropDownListControl.SelectedValue = "E";
                }
                
            }
        }

Hi,

I have a RadGrid with ExportToExcel functionality. That works very well.

My problem:

When I filter the data by EndDate (data between two EndDates). Then clicking on ExportToExcel button gives error "The string was not recognized as a valid DateTime."

Here's my markup:

 

Is there something I'm missing?

 

Hi,

I have a radPivotGrid, when i am running it on my local pc and on web server it is working fine.

But on mobile and some other device it is showing grid on half page.

 

I want only some of columns to be editable in my RadGrid. I have GridEditCommandColumn, GridBoundColumns (for them I dont want to be editable) and GridTemplateColumns (they need to be editable). Is that possible and how?

Such as title.

I think I'm missing something obvious, but I surrender.  I have an editor with the image manager tool enabled.  Below is my code behind code setting it all up, you can see that I create the directory if it is not there.  The image uploads successfully and is in the right directory.  However I am getting these three errors

• After an upload – You are trying to navigate to a non-existing folder or you do not have proper permissions…
• After I try the Image Edit - ImageEditor_Common_MessageCannotWriteToFolder
• After I try to Delete – The selected file could not be deleted because the application did not have enough permissions.

 Any hints would be greatly appreciated.

when creating groups dynamically to a grid with template columns, the application is throwing an unhandled exception error if the groupbe by column holds null values.  If the underlying data source is modified to replace null values with "" then the grid functions fine.  The way its to behave the columns to be grouped by can change so I need a way to handle nulls in the application code.  Does anyone have a solution for this?

 

 

                Dim ex As New GridGroupByExpression()
                For Each dRow As DataRow In objDS.Tables(2).Rows
                    Dim field1 As New GridGroupByField()
                    field1.FieldName = dRow("Column_Name")
                    field1.HeaderText = dRow("display_name")
                    field1.SortOrder = dRow("Sort_Order")
                    ex.GroupByFields.Add(field1)
                    ex.SelectFields.Add(field1)

                Next

                EditGrid.MasterTableView.GroupByExpressions.Add(ex)
