Cleanest way of setting max string length for text in GridView cells?

I want to make sure that each row in the table is the height of one line of text only.  I know you can set RowStyle-Wrap="false", but I also don't want any really wide rows.  I know I can go through each cell on RowDataBound or something and cut it to a particular length and then append an ellipsis on the end, but is there a neater way of doing the same thing?

Edit GridView Individual Cells in ASP.NET

The ASP.NET GridView allows for a row of data to be edited by setting the EditIndex property of the GridView, placing the entire row in edit mode.

You may not want the entire row in edit mode if you are using DropDownList controls for several columns in the EditItemTemplate. If each DropDownList has many options then loading them all at once may result in a sluggish page. Also, if your data structure is more like a 2 dimensional array rather than a set of rows, you may want to edit each cell individually.

Here I will demonstrate how to achieve this and also how to deal with event validation without disabling it.

gridview tablecell text emptystring in RowDataBound event when editing


HI and thanks in advance.  asp.net using vb, using a codebehind page.

I have a relatively simple gridview bound to an product table that displays great.  The problem comes when I choose to edit a row.  When I do so, the gridviews' RowDataBound event fires and the values of the text properties of the tablecells in the row evaluate to "" emptystring. 

I do notice that if I break within the GridView1_RowDataBound event during a refresh of the page, the values are there.  But again, when I hit the "Edit" button in the first column (the CommandField column) .  Text properties of the cells resolve to ""

 Here is the code for the event, followed by the gridview in the form (inside an updatepanel)

Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
        If e.Row.RowType = DataControlRowType.DataRow Then  ' not a header, footer row.. etc.
            Dim cellProductNumber As TableCell = e.Row.Cells(3) ' ProductNumber column

'>>>>> after clicking "update", even though a value displays in the gridview,
' the cellProductNumber.Te

How to return back to a specific page in a gridview list?

Hello,  I have a gridview with paging. So for instance, I'm on say the page number 10, and I open the form details on a specific record_id (link). After I update/submit the form, it returns to page number 10. But, if I go to another page, for instance page 5, and submit the form, it returns to page 10. I've tried some things, for instance history.back(), but it returns to the first page I went to, in this case page number 10 (or whatever the first page I go to). Hopefully this code helps to understand what I'm asking: <asp:GridView DataKeyNames="Referral ID" ID="gvList" runat="server" CellPadding="4"     ForeColor="#333333" GridLines="None" OnRowCommand="gvList_RowCommand"     OnRowDataBound="gvList_RowDataBound" OnRowDeleted="gvList_RowDeleted"     OnRowDeleting="gvList_RowDeleting" AllowPaging="True" PageSize="20"     AutoGenerateColumns="False" OnPageIndexChanging="gvList_PageIndexChanging"    OnRowCreated="OnRowCreated" AllowSorting="True" OnSorting="OnSort"> protected void gvList_PageIndexChanging(object sender, GridViewPageEventArgs e)        {   &nb

Get Text Value in Gridview from Invisible Field

Hello,  I've run into this before, but I was using a formsview and just changed the field to hidden.  If you've seen my previous post I am trying to get the value of a cell out of a gridview to a variable and here is the code: Protected Sub GridView1_SelectedIndexChanged(ByVal sender As Object, ByVal e As EventArgs) Handles GridView1.SelectedIndexChanged Dim varClientID As String = GridView1.Rows(GridView1.SelectedIndex).Cells(6).Text.ToString() End Sub This works perfectly if column 6 is visible, but because it's an id number (which is not the primary key) I do not want it visible, but changing it to visible="false" causes this code to return null.  Changing it back to visible and it works.I'm not sure why the visiblity of a control changes the functionality of it.Are there any other ways to get this data out?

Textbox in headertemplate gridview lost text in updatepanel

Hi everybody,I never post on this forum because since I write code in asp.net I always solve issues by finding solutions with other members who have the problem before me. But this time I don't know how to do...This is my problem : I have a gridview inside an updatepanel and i modified some headers in order to filter the collection.

Use value binded to gridview to show text corresponding to the value

 Hi, I am developing a website which populates a gridview from an arraylist through binding it to the gridview. This data can come from the database or just be entered by the user. However, I have codes to represent the text values chosen by the user to reduce the memory requirements of the database. Is there a way bind a value to the database and then display the corresponding text. The text will be already on the webpage in the form of a dropdownlist. Any help would be really appreciated! I can't seem to find anything on this on the internet. Regards,       Seamus

Can not reference text value in footer of Gridview control


I have been struggling with this all week end .... Yell

I am trying to implement adding a new record using the Gridview footer.

I have an example that works finethat I got from http://www.aspdotnetcodes.com/GridView_Insert_Edit_Update_Delete.aspx.

My situation is a little different .. as I am using master page and the Gridview is in a page derived from the master page.

I have tried:

Dim txtNewName As TextBox = DirectCast(GridView1.FooterRow.FindControl("NewName"), TextBox)

"NewName" is the ID of the textbox in the footer of the Gridview.

When I try referencing ... txtNewName.Text ... it returns a null value.

There must be some trick to referencing this .Text value when using the Gridview that is within a Content Place Holder that results when using a page that was created using a master page.


Thanks in advance fo any possible help with this problem ...

Capture large text return from Javascript function


I have a Javascript function that writes a large scale of text into a div for now, but then I need to capture the text and use it in code behind. I tried to use hidden field but it has size limit so it didn't work.  The text is shown in the page, but when I view source, there is no text in the div so I couldn't use code behind to read the text from the div even though runat is server because the text is always empty. Any suggestions? Thanks!!!
