Forms Data Controls :: GridView Updating - Despite UpdateMode "Conditional"
Nov 5, 2010
I'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...?)

I've got a weird problem: On a page, i've 2 updatepanels in conditional updatemode, with childrenastrigger set to true (default value).
A click on a IPostBackEventHandler control inside either the first or second updatepanel causes the 2 updatepanels to refresh.

I found this thread while trying to resolve my issue unfortunately this I can't seem to figure out the problem since I already have everything the way it should be.
I've got 3 updatepanels that each call a function on a .js file setup like this:
<asp:UpdatePanel ID="upPnlGeneralinfo" runat="server" UpdateMode="Conditional" ChildrenAsTriggers="true">
<ContentTemplate>
<script type="text/javascript">
Sys.Application.add_load(BindPageLoad);
</script>
Each have a different ID of course. Whenever a control calls a postback within the update panel it works, however in the js file I added a console.log("running the js file") and I can see that it's being called three times meaning it's all three updatepanels are being refreshed instead of just the one.
All the triggers are inside each of the respective updatepanels so I shouldn't need to add any triggers (I did just to make sure and it makes no difference). Shouldn't the UpdateMode=Conditional resolve this?
Also worthy to mention, none of my code behind ever calls any updatepanel.update(). I tried adding that for each control to their respective panels and that also made no difference.

I have 2 UpdatePanels in the same Page, and each one contains a GridView with some datta. I am using UpdateMode="conditional" because i only want the GridViews to be Filled when needed. So the data in each GridView is loaded only if the user asks for it, and it's not loaded again unless you need a change in the grid (sorting or page changing).
GridViews are filled with data from a DataBase, but I only read the data from the Database when needed. So, in first Page_Load, any data is readed. If the user wants to see the data in GridView1, the data in GridView2 is not loaded from the database, and viceversa.
My problem comes in this situation:
User enters the Page.
User ask for the data in GridView1 (UpdatePanel1 does the job)
User ask for the data in GridView2 (UpdatePanel2 does the job)
Now, the user can see both gridviews in the page. If he tries to change the page index or to sort data in GridView2, everything goes fine. The problem comes when he tries to change the page (or sort) in GridView1 (because in the callback to retrieve the data to GridView2, GridView1 was not filled, so the data the user is seeing is there because of a previous callback). The user gets an Event Validation Exception, and i don't know how to avoid it. I think it's because the server "thinks" that GridView1 is empty, because of the callback to load data to GridView2, where GridView1 was not filled.

I have a page with two updatepanels both which have thier triggers outside of the panels themselves - I am setting the triggers using in the pageload event. This is how it works - there is a repeater that holds a list of links which gets set when the page loads (this is outside of the update panel). The first udpatepanel has a trigger set to the itemcommand of this list of links - it then goes out and gets the sub links and fills a repeater that is located in the update panel. - so forgetting all about the second update panel on the page... If I set the panels updateMode="conditional" then it doesn't render till I click the link twice. If I put a breakpoint in the code I can clearly see that the code is executing and that there is no error but again... Nothing renders
- I click the link again it renders. If I take out the UpdateMode="conditional" statement all is well... But I don't want that cause I two update panels on the page.
The second one also has sort of the same problem - The trigger I have set for it the ItemCommand for the repeater in update panel one... when I click one of the linkButton's in the first updatepanel sure enougn I see the code execute return my results and all seems well however there is nothing rendered on the page. BUT!!! When I click one of the main links on top (remember these are trigger for updatepanel one) my second repeater inside of updatepanel2 is shows up on the page.
What is causing the partial postback not to render anything?
I know this is confusing so I hope I explained myself well enough. I will just post the ASPX so you can see how I am setting this up - I don't think you need to see the code behind... If anyone does then I will post it.
Again - all this is to with the updateMode - when I remove it (as I did in this code sample) it works and renders however I don't want both updatePanel to get updated at the same time.

I 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.

I am using a column named "bk_End_Date" in my gridview.I want to change the row color based on a condition.i.e. if the date value is within one week of today's date (upcomming days only), it's color should be red.I tried following method in RowDataBound Event of C#
//if (DateTime.Parse(e.Row.Cells[5].Text) <= DateTime.Today.AddDays(7))
//{
// e.Row.BackColor.Equals(Color.FromName("Red"));

I 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?

This 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" >

I 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)

I have a GridView with 5 fields. Only two of the fields are edittable (the others are READONLY).
I have an UpdateCommand as follows
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStrings:NHLPOOL %>"
SelectCommand="SELECT [PlayerID], [Firstname], [lastname], [Goals], [Assists], [Goals]+[Assists] as Points, [AsOfDate] FROM [PlayerStats], [Player] where [PlayerStats].[PlayerID] =[Player].[ID] ORDER BY Points DESC"
UpdateCommand="UPDATE PlayerStats SET Goals =@GOALS, Assists =@ASSISTS, AsofDate=GETDATE() WHERE PLAYERID = @PLAYERID">
</asp:SqlDataSource>
The issue is I want the PLAYERID GV column to be READONLY but I get a runtime error when updating if the PLAYERID is READONLY.
I get the error "
Must declare the scalar variable "@PLAYERID"."

I have a gridview and I want to update a cell with a session variable username. In the Gridview1_RowEditing event I have this code :
GridView1.Rows(e.NewEditIndex).Cells(5).Text = Session("username")
It does not give me any errors and seems to work but the grid view cell do not take this session. When I'm clicking on the edit hyperlink this event is triggered.

Having a bit of difficulty working this gridview update problem out - I have managed to get edit/update function working but instead of only updating the current gridview row it is updating the whole table I believe this is due to a missing where statement on my Update statement - to single out the row index of my grid row.When I configure my sql datasource I am using custom statements Here is my update statement
UPDATE SimpData SET store_nbr = @store_nbr, date = @date, data_type = @data_type, acct_1 = @acct_1, amt_1 = @amt_1, acct_2 = @acct_2, amt_2 = @amt_2, acct_3 = @acct_3, amt_3 = @amt_3, cheque_nbr = @cheque_nbr, cheque_amt = @cheque_amt, gst_hst = @gst_hst, qst = @qst, comments = @comments, uploaded = @uploaded

I have a gridview that holds 4 columns. in the fourth column there is a DropDownlist that holds three items.
I want my users to select one of the values and when they do the auto post back (which is set to true) should execute a method that updates the database selected row. But do i use the selectedindexchanged of the DDL or the Gridview? My head is totally thrashed so i imagine its really simple and im just over thinking it.
