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

Posted By:      Posted Date: August 31, 2010    Points: 0   Category :ASP.Net
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,

How to read a column of a sharepoint list to a text string field of infopath form?

My infopath form used to read these email addresses from a web service and web.config file. Now i would like to get these user email addresses from a contact list in a sharepoint server. I am trying to do this without writing any codes. Here is what i have done so far: 1. Adding a new "data connection to receive data from SharePoint library or List" where i selected Email Address column of the contact list. 2. I added a new Text Field and define a new rule with "Query using a data connection" defined above. When i try to access the newly created Text field above it always return empty as if the Query attached to it did not executed at all. What did i do wrong? Is there a better way? Thank you in advance for your help.

Varchar string to int - how to convert empty cells to nulls

Hi, I have a large table from which I want to convert certain columns from varchar to int while loading the table to another table. However, I run into problems when the input column contains empty cells. The SSIS data conversion data flow item can't handle these so I tried the script component. With the script component I can convert these empty cells to zeros but after that I'd need to use SQL update to update the zeros to nulls which in the case of a large table with over 3 million rows takes unnecessarily long. So, is there another way?

The maximum string content length quota (8192) has been exceeded while reading XML data.

Hi, I have been working on implementing a WCF service and have run into this problem with the maxStringContentLength.  I have read a bunch of posts here on how to correct it and none of them have worked.  I have updated my web.config in my local IIS5 published service to be maxStringContentLength="2147483647" and have updated my application's app.config to be maxStringContentLength="2147483647".  I delete all DLL's, rebuild, restart IIS, make sure all VS 2008 virtual webs are stopped, republish multiple times...even reboot my machine and I continually receive the following error message:The formatter threw an exception while trying to deserialize the message: There was an error while trying to deserialize parameter http://tempuri.org/qlStatement. The InnerException message was 'There was an error deserializing the object of type System.String. The maximum string content length quota (8192) has been exceeded while reading XML data. This quota may be increased by changing the MaxStringContentLength property on the XmlDictionaryReaderQuotas object used when creating the XML reader.

How Do I Not Include: myControl.GetType.GetProperty("Text") When No Property Window Setting?

Hi All, Posted below is code I'm using to generate a list of controls that have either a "Text" or "Caption" property. However, for certain controls in the resulting list, the property setting (Text/Caption) does not appear in the "Property Window" of the IDE when that control is selected. One example of this is the Systems.Windows.Forms.PictureBox control. Is there a way I can determine this and if so - how do I exclude these control(s) from my list?     Private Sub cmdValidateControls_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdValidateControls.Click         txtResults.Clear()         For Each ctrl As Object In Me.Controls             LogControl(ctrl)         Next     End Sub     Private Sub LogControl(ByVal ctrlIn As Object)         If System.Diagnostics.Debugger.IsAttached Then             If (Not ctrlIn.GetType.GetProperty("Text") Is Nothing) Or (Not ctrlIn.GetType.GetProperty("Caption") Is Nothing) Then                 txtRes

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?

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
