Hi,
I'm trying to go through the tutorial and work through the basics of telerik winForms. Its asks me to choose radForm from tools box, but all the controls of rad are available except the radForm. I'm using Visual Studio 2010 express edition and i've added the components manually.
It would be great if some one helps me here!
Thank You.

I am going mad with this. I can do it in gridview but I am battling to get it done in radGridView.
These lines are from a grid view in a winform that I should replace with a radGrid:
Basically I simply ned to get the content of the cell where I perform the mouse click. How you do the equivalent of the above using a radGrid?

private void DataGridView1_CellContentClick(object sender, DataGridViewCellEventArgs e) { var location = Convert.ToString(dataGridView1[e.ColumnIndex, e.RowIndex].Value); if (dataGridView1.Columns[e.ColumnIndex] is DataGridViewLinkColumn) if (e.ColumnIndex == 4) Process.Start(location); else if (e.ColumnIndex == 5) { int i = dataGridView1.CurrentCell.RowIndex;

I am using the example from here http://www.telerik.com/community/forums/winforms/gridview/radgrid-sum-expression-for-child-data.aspx to have a cell in my parent table (unbound) show the sum of the columns in a child grid. The problem I am running into is that ChildRows is off by 1. I.e. when CellValueChanged is called when I enter the amount, looks like the Row has yet to be added. Is there a better event to hook? I really want to update when the Row has been added.
Is CellValueChanged called before the ChildRows collection is updated?
Is CellValueChanged called before the ChildRows collection is updated?
private void gridExpenses_CellValueChanged(object sender, GridViewCellEventArgs e){ if (e.Column.OwnerTemplate != gridExpenses.MasterTemplate && e.Column.Name == "colAmount") { EvaluateTotal((GridViewRowInfo)e.Row.Parent); }}private void EvaluateTotal(GridViewRowInfo parent){ if (parent.ChildRows.Count > 0) parent.Cells["colRemaining"].Value = gridExpenses.Evaluate("Sum(colAmount)", parent.ChildRows);}

Hello everyone,
Here is my situation:
I have a dataset with a relationship between two tables. These two tables are load in an hierarchical way in the radgridview.
Now, in the child grid, I have a price column for each row.
I am trying to create a calculated field in the master grid view which will reflect the total of the prices in the child grid. The code I am using is like the following:
...
GridViewTemplate child = rdGvView.MasterTemplate.Templates[0];
rdGvView.MasterTemplate.Columns["TotalPrice"].Expression = "Sum(child.prodPrice)";
....
But this gives me an error which says {"Field name: child does not exist in the template."}
I am using the sum expression from this link: http://msdn.microsoft.com/en-us/library/system.data.datacolumn.expression(VS.80).aspx
where prodPrice is the column name of the table in the dataset which is imported in the radgrid.
Thanks,
Yash

Hi,
When I hit enter in the richtextbox, an empty line appears between the previous and the new line (like a new paragraph).
I would like to insert a 'normal' enter/new line when I hit enter.
Is this possible? Now the only way I can achieve this is when I hit shift + enter.
Best regards.

Hi,
I have a RadGridView in which there are 3 image columns. While exporting RadGridView to excel using ExportToExcelML class, all image columns are exported empty. Requirement is to display text instead of images. Is there a way to convert Image columns to text column or any other possible ways to achieve?

Also, I should export only visible columns in RadGridView and the text columns should be present only in the exported excel file and not to be displayed in RadGridView.
We are using Telerik Control version : 2013.3.1127.40

I am using RadDropDownListEditor. When the selection is made and dropdown loses focus, the cell reverts from the display text to the value.
How to keep the display text and not replace the cell with the value once the selection is made? I found an old thread back to 2011 which reported the same issue, however the suggestion does not fit my scenario, as I have to use a GridViewTextBoxColumn.
Here is the simplified sample of my cs codes. The designer is very simple, just a GridViewTextBoxColumn in a RadGridView control. A screenshot of the issue is also attached.
Any suggestion is appreciated.
Regards,
Shuping
