VS 2008 - Bind Data To Gridview / Hiding And Unhiding A Column

Mar 1, 2012

Right now when I bind data to my gridview, I have a column MemberNo that I use in the RowDataBound in another column for creating a link. Anyways, in the DataBound event i hide the MemberNo column. But I also have a routine where I need to loop through the rows and use the MemberNo. Can I unhide the column MemberNo to use for this routine and then hide it again? I assume I cannot use the data if it is hidden right?

Forms Data Controls :: Hiding A Column In A GridView?

Sep 23, 2010

I am having some trouble hiding a column in my GridView. For some reason when I do the following:

[Code]....

It hides the column correctly but also leaves an empty gray column at the end of my grid which is about 5px. Ideally I don't want to remove the column but hide it, but if I do remove it is it possible to remove the binded that column represents?

Forms Data Controls :: Hiding First 2 Columns Of A Gridview But Keep Column Location The Same?

Oct 25, 2010

using vb.net/asp.net 2005

I have a gridview with columns (pseudo-code):

<COLUMNS>
AuthorFirstname
AuthorLastName
BookTitle
YearPublished
</COLUMNS>

what I would like to do is to only show the AuthorFirstName and AuthorLastName columns for the first row of each author. I am easily doing this with:

[Code]....

However the issue that I'm seeing now is the formatting what happens is that after the first row that the Author names are hidden but then the BookTitle and YearPublished become the new cell(0) and cell(1) respectively which means that book and year are displaying underneath the author names columns. so my goal is to do 2 things:

1 have BookTitle and YearPublished render under the correct headers and

2. For the second row and after I would like the cell to appear the same as the background, I dont want the user to be seeing what looks like an empty cell or textbox there.

VS 2008 Hiding Columns In Gridview After Binding All Rows?

Jul 22, 2010

I am trying to set come columns to invisible after all of the rows are binded but I'm having trouble. I'm hiding columns that have empty data which I save in a session variable. This works fine. Then I tried changing the columns visible property using the ColumnByName routine in the DataBound but that must be the wrong event because I do not think the columns exist yet.

The columns are autogenerated btw.

Where can I set the columns properties after it has binded? Can i do this before the columns are autogenerated the the screen itself?

Forms Data Controls :: Bind Gridview Column To Nested Object?

Aug 2, 2010

If I have a list of contacts List<Contact> and a Contact object has an Office object property, I want to display a grid with columns

Contact Id, First Name, Last Name, Office Name

Where the sources of the above columns are respectively:

DataSource Controls :: How To Query A Table That Contains An XML Column And Bind The Data To A Gridview Object

Jun 21, 2010

I have tried to query a table with an xml column by using XQuery and I can't get the Select to work.

All my knowledge/understanding of the subject comes from this MSDN article:

[URL]

so I am probably overlooking something minor:

I tried this query Select col1, Phone.Query('element CellPhone {I am not sure about what goes here} I tried {data('Phone/cellPhone} from aTable Where Phone.Exist('/Phone/cellPhone/text()[contains.,"412-8977"]') = 1 This syntax is definitely not fun.

Forms Data Controls :: Hiding A Column In Datagrid?

Jun 24, 2010

I had a datagrid and I was hiding columns. This was working fine to show just the columns I wanted.

[Code]....

And then I realised I wasn't paging the data so I ticked that on then above code no longer worked. The Count was equalling 1 with the paging ticked on. Why would that be?

I also used the classic formatting and when I sort the columns the classic formatting goes funny, how can reapply the sorting to make it look classic?

GridView - Bind A Column To A Value In XML Field?

Jun 25, 2014

I have a data table that has several columns, one of which is an xml field. I want to bind a column in the gridview to a single node in the xml based on an xpath. The binding only needs to be read only, it won't be used to update. How would I do that?

So, given this data:

IDField, XMLData
1, "<Person><Name>FunkyD</Name><Age>110</Age></Person>"
2, "<Person><Name>Maurice</Name><Age>16</Age></Person>"

I want bind the first column of the grid to IDField - that's easy. I also want to bind the second column of the grid to the Name node of the XMLData field. The xpath would be Person/Name.

I'd want the grid to display:-

1 FunkyD
2 Maurice

NB, the node will only appear once in the xml field of each row. I want a row on the grid for each data row. What I don't want (and all I seem to be able find examples of on google) is to bind a grid to nodes that repeat within the same xml doc.

VS 2008 How To Tell What Column GridView Is Sorted On

Jan 4, 2011

I have a gridview control connected to a sqldatasource control. I am allowing the user to sort the columns in the gridview control. The user can click a row and visit another page. When they return I need to set the column sort again. I have seen that I can use the Sorting event to set the sort order of the data when I return to the page in the Sorting event. But before I leave the page where can i get the column it is currently sorted on along with the direction?

VS 2008 - Gridview Control - User Edit Only One Column

Mar 14, 2011

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];
GridViewstockcalc.DataBind();

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"
HeaderStyle-BackColor="#444444"
HeaderStyle-ForeColor="White"
onrowcommand="GridViewstockcalc_RowCommand" Height="150px"
Font-Size="Small" onrowediting="GridViewstockcalc_RowEditing"
onrowupdating="GridViewstockcalc_RowUpdating">
<Columns>
<asp:CommandField ShowEditButton="true" ShowCancelButton="true" />
<asp:TemplateField HeaderText="ticker">
<ItemTemplate>
<%# Eval("ticker")%>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox runat="server" ID="txtticker" Text='<%# Eval("ticker")%>' />
</EditItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="fhlb_ID" HeaderText="ticker" ReadOnly="true" />
</Columns>
