How To Change Column In Gridview Into A Hyperlink To A File

May 07, 2009 02:01 PM

I have a basic vb.net webpage that returns data from my sql database and fills a gridview. One of the columns is the name of a file. I'd like to modify the gridview and make the name of the file "clickable" so that the user can see see the name file they uploaded, and if they want to, click on the filename and open the .doc or .xls. Is this possible?

My columns for the gridview are:


I want to display the FilenameatUpload, since it's the name of the file the user will recognize, and make it clickable to then pull up the actual File, which is the hidden bound field of "FileName" (I modify the name of the file when they upload it to ensure it's unique.

Change GridView Column's ItemStyle And AlternatingItemStyle?

Feb 12, 2009 03:03 PM

I have a GridView:

And my gridResults_Sorting method:


This works perfectly if I wanted to change all the cells in the column to a single color.

However, my ItemStyle and AlternatingItemStyle are different; one has a blue background, the other has a white background.

So when it's sorted, I'd like them to have a dark blue background and a gray background.

How is this possible? I can only change the ItemStyle for the entire column.

Forms Data Controls :: TemplateField Change Itemtemplate Label CSS Depending On Column Value For Each Row In Gridview?

Jan 28, 2011 10:48 AM

I was wondering if anyone could help me. I have a template field which has four itemtemplates that each hold a label in a gridview. These labels are always constant with the same strings. What I want to do is change the css formatting of these four labels depending on the value of a column. So the css formatting would have to be done for each row, not the whole column. I bind the gridview to a dataaccesslayer so there is no sqldatasource on the page. Does anyone have any idea how to do this and where it would be done. I will have the dataview with the data sorted in the correct order. The actual column that is used to alter the CSS will not be in the gridview although I could assign it to the datakeyname if that makes it easier as the data is not sensitive.

VS 2008 - Gridview Control - User Edit Only One Column

Mar 14th, 2011, 03:22 PM

I have a gridview control on .aspx page. Situation is, the columns in the gridview control are not databound. I query the database and load the gridview control using the following code.

GridViewstockcalc.Visible = true;
GridViewstockcalc.DataSource = dataSetstockcap.Tables[0];

The gridview control shows about 13 columns from the database. But we want the user to be able to edit only one column. Rest of the 12 columsn should be read only. When the clicks one Edit button button, as usual the Update and Cancel buttons should come up. It is not happening. Only the _Rowediting event is getting trigged. Following is the code from my .aspx page. I don't know anything about template columns and not sure if I have to use that concept in my situation.

<asp:GridView ID="GridViewstockcalc" runat="server"
onrowcommand="GridViewstockcalc_RowCommand" Height="150px"
Font-Size="Small" onrowediting="GridViewstockcalc_RowEditing"
<asp:CommandField ShowEditButton="true" ShowCancelButton="true" />
<asp:TemplateField HeaderText="ticker">
<%# Eval("ticker")%>
<asp:TextBox runat="server" ID="txtticker" Text='<%# Eval("ticker")%>' />

Forms Data Controls :: How To Control Gridview's Column Width

Nov 24, 2009 07:48 AM

How do I control the gridview's column width wherein my gridview is dynamically populated from a dataset. What I want to achieve is to have a somewhat uniform column width for all column entries. I have already tried specifying the Itemstyle-width = "desired column" width but still the content of the dataset still dictates the final width of the column. When I also try to set the ItemStyle-Warp = false, it does not still give me the desired effect because it will just increase the column width to fit the content of the dataset. I think to achieve my desired effect and since some contents of the dataset are long, the solution would be to truncate the dataset prior to binding it to the gridview but I don't know how.
