I have created a custom webpart using a Sharepoint InputformTextBox control to enter richtext items.

I have to insert an image at the cursor position in InputformTextBox control's RichTextEditor window.

I have an image button, on click of it, I am trying to insert the image at cursor position in RTE window.But i could not get the current cursor position.

Here is the code,

protected void btnimgnew_Click(object sender, ImageClickEventArgs e) {
string newImage = ""; txtcontent.Text = txtcontent.Text.Insert(indexPosition, newImage.ToString()); }

How to get the cursor position in InputformTextBox control's RichTextEditor window?

Thanks.

Current cursor position is javascript.

var rng = RTE.Cursor.get_range().$3_0;

The above will select the range of text selected. This will insert something after that range (in this case, "something" defined by the variable a):

 SP.UI.UIUtility.insertAfter(a, rng);
