Forms Data Controls :: Set Current Gridview Page To Selected Row's Page After Sort / Edit?
Jan 20, 2011
I'm new to ASP.net (and coding in general) and I was very impressed about how easy is to learn enough to create something useful :)
Unfortunately, now I'm stuck on a problem involving gridview sorting and paging: I created a master gridview bound to an sqldatasource, I enabled sorting and paging and then I linked it to a detailsview to enable editing and inserting.
In addition, I set up two other gridviews whose datasources depend on the master gridview.
When a user selects a row and modifies it in the detailsview, the sort takes place and the row is often moved to another page. This can be a little confusing, especially because there are other controls relying on the selected row of the master gridview.
There's a way to find and select the page of the selected row after gridview's databind and sort take place? I tried creating a dataview to search the index of the selected datakey in the databound event of my gridview, but it doesn't work, because it seems that the rows aren't sorted yet. Maybe I should choose another event?
i have a gridview that has the ability to sort by each of the columns, but suppose if i'm on page 2 of the results and sort any of the columns, it jumps back to page 1. is there a way to keep it on page 2, still have the sorted date work?
I have two gridviews on same page - If a record is selected in Gridview1, I need to unselect a record (if one is selected) in Gridview2 - and vice-versa.
I have a GridView known as GV_R001 with IssueType, ActID, IssueID cells. I want to Merge the similar IssueType cell accordingly. How do i merge and also sort the IssueType cell accordingly. The following is my codes:
Protected Sub GV_R001_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GV_R001.DataBound For rowIndex As Integer = GV_R001.Rows.Count - 2 To 0 Step -1 Dim gvRow As GridViewRow = GV_R001.Rows(rowIndex) Dim gvPreviousRow As GridViewRow = GV_R001.Rows(rowIndex + 1) Dim cellCount As Integer = 0 If gvRow.Cells(cellCount).Text = gvPreviousRow.Cells(cellCount).Text Then If gvPreviousRow.Cells(cellCount).RowSpan < 2 Then gvRow.Cells(cellCount).RowSpan = 2 Else gvRow.Cells(cellCount).RowSpan = gvPreviousRow.Cells(cellCount).RowSpan + 1 End If gvPreviousRow.Cells(cellCount).Visible = False End If Next End Sub
Apart from that, after sorting i want to calculate the amount of IssueID are in a particular IssueType and display in a cell called "Total". Is it possible to do so? By the way, I am using Web Developer 2008, VB.net.
Initially I display all the records in the gridview. Then based on the search I fetch certain records and display it.. When I try to edit any retrieved record, the control automatically tries to edit the first record instead of editing the selected record.. What should I change in the code to make it work?
I have a page with a gridview control that shows files that have been uploaded to our site. The name of the uploaded files, who uploaded them, and if they have been downloaded, etc are stored in a table. The gridview is bound to the table through a sqlDataSource control. I have a button column in the gridview that downloads the file associated with a row when the button is clicked. All that works well. I have a check box column that shows checked if a file has been downloaded. When the download button is pressed.
the file downloads and then a short routine is run to update the downloaded field in the uploaded files table to set the downloaded field to true. This is done through a command string. All this works. Here is the question. After the update is run I do a databind on the gridview to update it. The databind is run in the PageLoad event is the page is a postback. This does not cause the current row to show downloaded =true (checked). If I refresh the page in the browser then it displays correctly.
im not sure why but my gridview seems to have stopped working in all areas of Editing, Deleting, Sortinging and i cant click the page number to switch between pages.Ive looked up numerous tutorials and on forums and still cant seem to find a solution that works for me. I have the edit delete sorting and paging check boxes selected.
When i click on any of the links nothing happens. not even a refresh.
Just spent about 8 hours googling and looking through this forum for a solution on how to make sure that I can dynamically sort. Here is the situation.
I have 1 Gridview that displays 10 different scenarios based on what button is clicked.
I am also returning only top 10 records. I am doing all of the data binding pragmatically. So I have BoundFields, HyperLinkFields etc.
I also want to sort some records. When I change DataSource SQL statement the gridview somehow remembers what the last sort value was and it errors out saying that value "x" cannot be sorted because it does not exists.
Here I get an error that says that the data source does not support sorting? Doesnt it say gridview1.allowsorting = false;
I also tried gridview1.sort("", SortDirection.Ascending); This does nothin... except query my database one more time because i have a onSorting event that looks like this:
[Code]....
Here is an example of just one of those SLQ statements inside GetSQLQuery:
i am creating a print view using checkboxes that a customer uses to select which items they wish to print. I am having difficulty transfering the selected gridview items to another page. I was using crosspage post.
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 currently have a GridView control on my aspx page with paging enabled and I need to loop through the entire row collection/count to process the selected records. With my current code, it will only loop through the current page of GridView row.
foreach (GridViewRow data in grid.Rows) { //here is my code }
I am having 2 web formsand will have a drop down list on those web forms. If i select a value from drop down and click on ok i will get tranfer to next page. In that page i will have a drop down with the same values in the previous form . What i need is i would like to disable the selected value in the previos form and would like to display the remaining normal.
I have a web user control with DataList control in it. In my .aspx page, I have a report header, an empty panel as a place holder, a report footer.In my .aspx.vb file, I'll loop through a list of departments. Within each department, I'll load a label to display the department name and the user control for the data, and add both the label and user control to the panel. So there are two variables: the number of departments and the number of records in a user control.
Now I need to display the current page number and the total page number in the report footer. Is it doable? How? I'm thinking of this approach: declare a page variable count, count the number of department name labels and the number of records in a user control. When the total count reaches a number, such as 20, I'll break the page. This way, I can get the the page current number and the total number of pages. But how to add a page break to an asp.net page?
