When I click on my GridView header "End Time" all the rows which contain the string "N/A" disappear.
Here is my code:

Note: GetSortDirection returns "endTime ASC" or "endTime DESC" and save in ViewState:

Then I fill the DataAdapter and use the ViewState info to sort it:

I have a listview and inside the listview I have a gridview. I'm binding data to the listview, then on the listview itemdatabound I'm binding the gridview. I want to make the gridview editable so I have an edit template and an edit command button. I have the event rowediting and inside there I set the edit index. Now normally I rebind the control and everything works. But if I rebind this gridview, nothing happens.
I can trace through the rowediting and everything is working. It's setting the edit index, it goes through the databind and gets the right data and binds it to the control. What is happening? Why isn't my rebound edit mode gridview showing up?
I have a GV that is populated via a reader: Using reader As SqlDataReader = cmd.ExecuteReader() I have autogenerate edit button=T but it will not go into editmode. Must I create template to handle this?
View 4 RepliesI have a Gridview that shows my data, I allowed it to have Editing and Sorting. I have achieved refreshing my GV with <META HTTP-EQUIV="Refresh" CONTENT="15">. however, when I Edit and it hits the time to refresh, I loose the Edit mode and starts at the beginning of the grid (I need to find the data again.) Is it possible to still have the refresh (15secs) then when Iam in EditMode, the Refresh stops, then after I have clicked UPDATE. the refresh time starts to count again. (i use VB)
View 7 RepliesI don't know how to do this, I think I need to find the control first.

I have a page with an UpdatePanel in wich I load the menu selected Layout pages, and the layouts loads its contents dynamically.
It works fine, but when I load a Layout that has an Multiview control, the code behind of the Layout don't come in into the if(!Page.IsPostBack), ok, I fixed it with if(multiview.ActiveViewIndex==-1) multiview.setactiveview("viewName").
In the Multiview I have a ListView, in the listview I have Linkbuttons that opens another view and shows the information of the specified row dynamically.
when I click in the link so the page disappear from the update panel... why? I do not a full postback of the page, so I think I don't need to reload that page on the update panel... Right?
I have 2 pages page1 and page2, page1 has a button and page2 has a multiview with many viewswhat I need is:when I click on the button in page1 I want to go to a specific view in page2 ex: view3

I have a gridview in which i have declared one static templatefield (with some button ctrls inside) in design itself.
I add the remaining columns to it as a dynamic templatefield by inheriting the ITemplate interface.
My problem is that now when i cause some postback for the firsttime after the Gridview is bounded, it works fine. But when i cause some postback for the second time, all the controls in the static templatefield disappears.
below is my code

I have a checkbox column in a Gridview that is added in the aspx and the other columns are added in the code behind. The checkbox is a choice to print the record or not. When the print button is pushed the page posts back and the checkboxes are gone.
I have read that you have to re-add the checkboxes on postback, but where do you do that and how do you retain the viewstate values - checked/not checked? I have tried everywhere - PreInit, PreLoad, PreRender... I can't get the viewstate values to appear anywhere. The checkboxes can be added just about anywhere but the vaules are set to "unchecked" by default... no values ever come back no matter where I re-add them.
I already implemented the dynamic templatefield which will re-created in every postback. Everytime I make a postback in the page I see no problem but when I click my imagebutton inside the gridview then the dynamic templatefield disappear.
To double check if it is really gone at all I just select the second page of the gridview using my customize paging using dropdownlist outside the gridview and the templatefield with its correct data reappear again.
I already put a variable inside the rowcommand to see if the number of columns are the same with the number of columns the gridview render together with the dynamic templatefield during debugging and it is there but cannot render that templatefield in the client.

I am trying to put the select command in code behind:
sdsAdd.SelectCommand = String.Format("SELECT Classes.ClassId, Committed, CallNumber, SubjectArea, CourseNumber, SectionNumber, GradingBasis, NumberOfUnits, NetId FROM Classes INNER JOIN EnrollmentAdjustmentClasses ON EnrollmentAdjustmentClasses.ClassId=Classes.ClassId
WHERE AllFormsId='4' AND SectionId='1' AND NetId=@NetId AND Committed='True' AND EnrollmentAdjustmentClasses.FormId={0}", Request.QueryString["FormId"].ToInteger32());
gvAdd.DataBind();
When I do that, then click edit to edit the selected item, the item disappears from my gvadd. What am I doing wrong?

I have a GridView attached to an ObjectDataSource (returning a DataTable) in a UserControl. The code is really simple. Data comes down fine when the page is first rendered. When I click on Select or Delete (inside TemplateFields), RowCommand is supposed to fire but it doesn't, the page goes straight to Page_Load. I literally have 0 other event handlers that are set on this control and everything else in the codebehind shouldn't even fire if it's a postback. Also on postback, the Select and Delete buttons disappear. It looks like the TemplateFields are still there but they're empty. The data fields (all of two columns) post back fine.

Basically, I have a gridview and it has RowEditing function, which to be fair has two lines of code
GridView1.EditIndex = e.NewEditIndex;
GridView1.DataBind();
When I press the edit button from one of the row in gridview, it hides the whole gridview!
To bring it back, I have to call the function which does the binding and suprisingly, it loads back in edit mode!
I have a Gridview with edit/delete button & in row data one field is a month value.
I want the edit/delete button in that row to disappear if the month in the row is past month.
How could I do this ? I have set the label1.text = current month but I do not know how to set the edit/delete button to be visible/invisible on the condition of the data in the row.
I'm using a Gridview in VS2008 framework 2.0 to edit a field with standard edit/save/cancel buttons on each row. I have a textbox named TextBox1 in an EditItemTemplate tag, it's value is binded to my field with '<%#Bind("LOGIN_NM")%>'. This is a simple form a took from an old project. My problem is when I try to read the textbox in the GridView1_RowUpdating event, it keeps returning the original value and not the modified value. I spent some time figuring the cells, controls and all so I'm sure I'm reading the right textbox, I have only one. I also tried using:
CType(row.FindControl("TextBox1"), TextBox).Text but I can't get the modified text to store in the database. The exact same thing works in the old project.
by default, my formview loads up to Editmode and it looks like this:

My Page_load looks like this:

Problem is if binding is not ran during postback here, buttons on the ItemInsert mode DO work, but the button on the ItemEdit mode DON'T work. However, if I don't bind the fv1 here during postback, controls will not load on the formview ItemEdit mode and databinding will not occur.
i have a detailstview and sql datasource I am retrieveing the data so far no problems but afteradding a dropdownlist in edit mode and clicking edit button I get this error"

I have a simple FormView (fvDespatchPart) which updates the status of an order and it's despatch date; the despatch date being retrieved from a textbox (txtRentalDespatchDate)
held within the FormView. The FormView's DefaultMode is set to Edit.
I have been trying to set the default entry for txtRentalDespatchDate to today's date in the code behind, using:
Dim dtNow As Date = Today()
Dim txtRentalDespatchDate As Webcontrols.Textbox = fvDespatchPart.FindControl("txtRentalDespatchDate") [code].....
I have had no trouble doing this in the past with FormViews whose default mode is set to Insert or Item, but in Edit mode it just does not seem to want to co-operate. I have read a few help posts, and have tried:
Putting that code in LoadComplete, PreRender, PreRenderComplete Page events, as well as the FormView's databound event. I've also tried nesting it within a ...
If fvDespatchPart.CurrentMode = FormViewMode.Edit Then
End If
... just to make sure if is in the right mode.
Nothing yet has resulted in anything but the same old error.
