Forms Data Controls :: Can Write But Not Read CssClass Of A GridView Cell
Feb 24, 2010I have a GridView where some of the BoundFields have a CssClass applied:
<asp:BoundField ... ItemStyle-CssClass="foobar">
In the rendered HTML it looks like <td class="foobar">
But when I try to read the CssClass programatically in an event like RowCreated or CheckboxChanged or PageLoad it returns nothing:
For Each row As GridViewRow In gv.Rows()
For Each cell As TableCell In row.Cells()
ltlMsg.Text += cell.CssClass
Next
Next
(gv is my GridView and ltlMsg is just a Literal for displaying the results)
If I replace cell.CssClass with cell.Text it does display results, so the code is running.
If I change it to cell.CssClass="test" it does set the class of the <td> elements. It just can't seem to read them.
I must have missed something obvious - I've tried putting it in various different events but nothing seems to work. I assume the CssClass must get set at a later point in the event cycle than I have tried. Can anyone recommend a link to documentation that shows the order in which all the events fire?
Eventually I want to use this to show or hide certain columns in the GridView based on whether a CheckBox (outside the GridView) is checked or not.

Forms Data Controls :: Conditional Formatting In Gridview?
Feb 2, 2011I have a gridview on my aspx page. I know we can format gridview row in rowdatabound() of gridview. But my problem is bit different.
In my gridview, i have a column customer code, a single code can repeat more than once successively. I want for one customer code, row color should be blue and as soon as code changes colour should be yellow for that code. Similarly when code changes again color should be blue again.
In this way color of my gridview rows should be blue and yellow alternately based on my customer code.I have arranged customer code in order by using sql order by clause.

Forms Data Controls :: Conditional Eval Statement In Gridview?
Nov 18, 2010I have a conditional Eval statement in a Gridview that returns a boolean result to display an image if two datafields(strings) are identical:
Visible='<%# Eval("customerA").Equals(Eval("customerB")) %>'
Works great except I don't want the image to display if both datafields are empty. How can I add that logic into this Eval stmt?

Forms Data Controls :: Conditional GridView Mouseover - Mouseout Template Field?
Mar 9, 2011This is what I have - it works:
<asp:GridView ID="GridView10" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource10"
<asp:TemplateField HeaderText="File Photo" SortExpression="Pic_Number">
<ItemTemplate>
<asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/{0}.jpg")) %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Item_Count" HeaderText="Stock" SortExpression="Item_Count" InsertVisible="False" ReadOnly="True" >
Conceptually what I want: (item count is a BoundField called in the GridView )
<asp:GridView ID="GridView10" runat="server" AutoGenerateColumns="False" DataSourceID="SqlDataSource10"
<asp:TemplateField HeaderText="File Photo" SortExpression="Pic_Number">
<ItemTemplate>
( IF "Item_Count" > 50 )
<asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/{0}.jpg")) %>' />
( IF "Item_Count" < 50 )
onmouseout : <asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/StockLow.jpg")) %>' />
onmouseover: <asp:Image ID="Image1" runat="server" ImageUrl='<%# (Eval("Pic_Number", "http://.../images/{0}.jpg")) %>' />
</ItemTemplate>
</asp:TemplateField>
<asp:BoundField DataField="Item_Count" HeaderText="Stock" SortExpression="Item_Count" InsertVisible="False" ReadOnly="True" >
Forms Data Controls :: GridView Conditional Formatting Based On Duplicate Values?
Jun 2, 2010I have a gridview containing serial-numbers.
I would like to format the background each data-row that contains a duplicate serial-number value.
I'm planning to do this using a DataBound event handler.
So, in English:
Set background colour of THIS_ROW to red where the Serial_Number of THIS_ROW is the same as the Serial_Number of ANY_OTHER_ROW.
All rows with duplicate serial-numbers would be red.
I'm not sure how to write the code for this event.
The gridview is bound to a SQL datasource. Getting the dupes in SQL is easy:
SELECT Serial
FROM Table
GROUP BY Serial
HAVING (COUNT(Serial) > 1)
How To Set The RowStyle Of A GridView Row Depending On A Property Of The Object
Jan 20, 2010I'm currently using a GridView and I want to set the CssClass for the Row depending on a property of the object that the row is being bound to.
I tried the following but it does not work (see comments):
[code]...
Now I could simply handle the GridView's RowDataBound event and change the css class of the row there...but I'm trying to keep a clear separation between the UI and the page/business logic layers.
GridView RowStyle Dependent On Property Of Item Row Bound To?

Forms Data Controls :: GridView Updating - Despite UpdateMode "Conditional"
Nov 5, 2010I've got 2 gridviews on a page. One is inside an update panel with update mode set to Conditional
<asp:UpdatePanel ID="UpdatePanel1"
UpdateMode="Conditional"
runat="server">
However, in the 2nd gridView, I'm clicking on a thumbnail image, in order to see a full size image by recalling the page and adding a QueryString e.g. Content.aspx?Image=Pic1
This all works fine.
However, when I am on the 2nd page of records in the first GridView, calling the page from the images in the 2nd gridview causes the 1st gridview to go back to the 1st page of records. Despite being inside a conditional UpdatePane.
(Perhaps theres a way to update the images only, without calling the page again...?)
Forms Data Controls :: Put A ListView Onto A Webform But Got An Error - The 'CssClass' Property Cannot Be Set Declaratively
Feb 21, 2011Using VWD 2010 Express.
I tried to put a ListView onto a webform but got an error right after that:
Error Creating Control - ListView1
The 'CssClass' property cannot be set declaratively.
BTW, does ListView support horizontal/vertical scroll bar? As I might have about 50 records in maximum, so need to have horizontal and vertical scroll bars. But do not need paging.

Forms Data Controls :: Put OR In Conditional Inline Code?
Mar 15, 2011EXISTING CODE:
<asp:HyperLink ID="HyperLinkG102" runat="server" Visible='<%# (Convert.ToInt32(Eval("L_ID")) != 77777 ) %>' Text='<%# Eval("L_GalleryName") %>' NavigateUrl='<%# String.Format(".... /findlink.aspx?linknum={0}", Eval("L_ID")) %>' Target="_blank" Font-Size="9"
ForeColor="Blue"></asp:HyperLink>
Is there anyway to put an OR conditional in the Visible text?
( Visible='<%# (Convert.ToInt32(Eval("L_ID")) != 77777 ) OR Visible='<%# (Convert.ToInt32(Eval("L_Rank")) != 0 ) %>' )
Forms Data Controls :: Conditional Binding Of Selected Value In Formview DDL?
May 4, 2010I have a sql-bound formview with three DDL's bound to individual SQL datasources. In edit mode, I want to set the selected value to the formview's value, and this works:
<asp:DropDownList
ID="ddl2"
runat="server"
DataSourceID="ddl2lDS"
DataValueField="Name"
SelectedValue='<%# Eval("Name") %>'
/>
But it only works when there's a match between what's in the formview's DS and the DDL's DS.
Unfortunately, there may be instances where the the formview's DS may return a null value or a value different from the DDL's datasource...and when that happens I receive a compilation error like:
'ddl2' has a SelectedValue which is invalid because it does not exist in the list of items.
Parameter name: value
What do I need to do to trap that condition before attempting to set the selected value? Do I need to set the selected value of the DDL in formview's dataBinding or dataBound event, by looping through the DDL and checking for a match first?
Forms Data Controls :: Conditional String Formatting Within Repeater?
Mar 29, 2011In my repeater I am attempting to set the label format based on a value from my datasource. The following line from my repeater is straightforward enough but now how would I modify it if I wanted the "C2" statement in the ToString to pull from a field in my datasource named "MyFormat" which would contain either the C2 or N0 value? Basically switching the formatting for that label between currency and a double?
<asp:Label runat="server" ID="lblValue1" Text='<%# Convert.ToDouble(Eval("MyValue")).ToString("C2") %>'></asp:Label>
I've attempted to simply insert a statement such as Eval("MyFormat") in place of the "C2" statement but to no avail.

Forms Data Controls :: Conditional Formatting Listview For Edit Button?
Mar 13, 2011I want to have a listview with conditional formatting on its edit and delete button.So, in nutshell, I want to check if the writer of post is equal to session("memberid"), then the edit and delete button will be appeared, else, it will show hidden.

Forms Data Controls :: Conditional Control Based On Repeater Content?
Oct 8, 2010I have a repeater control with a delete button on each row. I also have a link on the same page (not within the repeater) that I only want to be visible when the repeater contains at least one row.
My problem is that, when the delete button on the final row is clicked, this triggers a postback during which the ItemCommand event is called to process the delete click. However this event is processedafter the Page Load event in which I would normally render or not render the conditional link. So I don't know at the time I'm rendering the link whether the user has just deleted the last row.
Am I misunderstanding the chain of events or is there a better way of handling this? Could I, for example, determine from the Sender & e arguments available within the Page_Load event, that the postback has been triggered by clicking the delete button in the repeater? The only other way I can see of dealing with this is to force a second postback once the final row of the repeater has been deleted which seems like overkill.
