Limit amount of text shown in data column

[Ron]

Hi,

Can you tell me if there is a way to limit the amount of text shown in rad grid? For example; a particular data field has a string of text about 200 characters in length, but on the actual data grid I only want to show the first 50 characters in the data column. How would I do that?
Looking forward to assistance.

Thanks,
Ron.

Hello,

<telerik:GridBoundColumn DataField="Name" HeaderText="Name" UniqueName="Name"
                 >
                   </telerik:GridBoundColumn>

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
        {
            if (e.Item is GridDataItem)
            {
                GridDataItem item = e.Item as GridDataItem;
                if (item["Name"].Text.Length > 200)
                {
                   item["Name"].Text = item["Name"].Text.Substring(0, 200);
                }
            }
        }

Let me know if any concern.

Thanks,

Hello,
You can achieve this by using following code.

.aspx:

<telerik:GridTemplateColumn HeaderText="Short Description"
DataField="Description" SortExpression="Description" AllowFiltering="true" UniqueName="Description" Visible="true">
     <HeaderStyle HorizontalAlign="Left" />
     <ItemTemplate>
          <asp:Label runat="server" ID="lblDescription" Text='<%# Eval("Description") %>'></asp:Label>
      </ItemTemplate>
      <ItemStyle Wrap="True" HorizontalAlign="Left" />
</telerik:GridTemplateColumn>

.aspx.cs

RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
     if (e.Item is GridDataItem)
     {
          Label lblDescription= (Label)e.Item.FindControl("lblDescription");

          if (lblDescription.Text.Length > 50)
               lblDescription.Text = lblDescription.Text.SubString(0,50);
    }
}

Above code will display first 50 characters if the characters are more than 50.

Let me know for any concerns.

Hello Rakesh.

Its also work but if you take one more Lable to showing the data then it will affect the Grid's performance (on Live Server).

Please compare the page source code in both sample.

Hi Jayesh,

I want the same scenario but only thing I am using RadEditor control.

In RadEditor control I have some formatted test(Bold,Italic). Now from the formatted content I want to show the only first 50 character. If I will try the above code which mentioned you It will not bind the formatted text.

I am getting from database

Content Saved in Database:
<strong><em><span style="font-size: 20px;
text-decoration: underline; color: #ff0000; background-color:
#ffc000;">WOW <span style="color: #000000; background-color:
#ffffff;">12356432569874563215346985763259874561235478965324</span></span></em></strong>

How to achieve this ?

Thanks,

Harish P

Hi Harish,

The question you posted has already been answered in the following forum thread: http://www.telerik.com/forums/radeditor-shows-only-50-character-from-content. I would recommend continuing the discussion there as it will be easier to track the information on the case when it is in one place.
