I am working on a Webbased project, where we have a Master page with some child page. In the child page there is GridView control, Footer of this Gridview control have some TextBox control to get the input value from user and insert into database. Once the data is inserted into database. We are reloading the inserted data into the same Gridview control, But Gridview control is hot Binding/showing up the recently added record.
I debugged the code and seen the Dataset which is getting the data fron database have the updated row but after binding to Gridview control. The Gridview control not refreshing the data. This is happening while we have Master page and child page.
I have a gridview which is fairly straight forward... I've added paging to the gridview which functions correctly. However, after clicking any one of the page buttons (next page/last page), it appears some sort of a label is being displayed in my web form saying "NewPageIndex: 1". This changes from page to page displaying the actual index of the page. Why is this displaying? The only thing i can think of is the size of my gridview (Right now set to 1500 lines per page) . here is my gridview control html code:
using vb.net/asp.net 2005 and SQL Server 2005.I had similar issue yesterday: I created a unique index on a table to prevent duplicates when user tries to edit existing records in a gridview.This works fine and I am seeing the "cannot insert duplicate key row message...." however I need to catch the exception because I do not want to display the table and column names.I have this set up but its not catching the exception, the exception is displaying but not my version, does anyone know in what gridview event and how I can catch and customize this exception? what i have now (but not working ) is:
Right now I have a gridview with databind. My menu item consist of the 7 days of the week. Everything works fine except for one thing, the page index. Right now by default it loads the results for Monday. If I click on Pg 2 for Monday, and then I click on Tuesday, the page number stays at page 2 and the data remains the same. I have to click on Pg 1 or Pg 3 before the data would refresh and change the result to Tuesday's data.
I've tried adding databind() to the MenuClick event but if Monday has 3 pages, and they click on Tuesday which only has 2 pages, it would give me an error. Also the adding of the Databind() still doesn't fix the page index when I click on a different day.
How do I reset the page index when the user clicks on the day.
I have a gridview with paging. I have a style set for a selected row (highlights the row in light orange). What i would like to do is that each time a user chamges the page, the selectedIndex & selectedRow automatically becomes the 1st row of the selected page. So i would like to see the orange highlight on the 1st row of the page to indicate that the row has been selected.
I have tried GridView1.SelectedIndex=0 but this only seems to select the index of the 1st record in the whole datagrid. Does anyone know of how to set the 1st row of the page to the selected row each time the pageindex is changed?
I have a menu. I use the menu's menuitemclick event to create a gridview (several actually) that is then added to a panel for display.The gridview paints perfectly until I try to add paging.I have successfully used paging and sorting declaratively for years, but this is my first attempt to do everything in code.When the gridview tries to databind, it throws an error:
[NullReferenceException: Object reference not set to an instance of an object.] System.Web.UI.WebControls.GridView.get_StateFormatter() +25 System.Web.UI.WebControls.GridView.BuildCallbackArgument(Int32 pageIndex) +56
I've a gridview control that has paging enabled. The control works completely fine in IE. However I was shocked to learn that the same page is not working on firefox i.e when I click on a page index the grid doesn't show selected page's data!
The page is posted back when I click a page index, I've checked it in debug mode as well. However the code for "Page Index Changing" is never fired!
'm using a gridview with paging and sorting in asp.net (language = VB).The gridview shows all the artists in my database. I've added a searchbox above my gridview, so users can search for certain artists by name.The search option works. If I enter the name: John --> it shows the artists who have the name John.Now for the problem:If the user filtered the gridview (for eample searching for John) and switches to another page of the gridview, the gridview is again filled with all the artists instead of the artists that are named John.
VS2008 ( vb.net ) I created a test page with a gridview and link button on it. in code behind i placed the following code
[Code]....
this works perfectly .. however, if i set up the same page, but use a master page as well ... then that code doesnt work. GridView1.Rows(e.CommandArgument.ToString).Cells(15).Text.ToString() is empty
I am using grid view with row "data bound event" at row row data bound i am using some function with loops to fill drop down of grid view in template columns. grid view gets populated with selected index change event of drop down. my problem is the asp.net page is getting slower i mean when grid populates its taking some time and some time page get hanged what to do to get rid of it?
I have gridview control. visit [URL] but when i change page index of this i get error the following error
Failed to load viewstate. The control tree into which viewstate is being loaded must match the control tree that was used to save viewstate during the previous request. For example, when adding controls dynamically, the controls added during a post-back must match the type and position of the controls added during the initial request.
I have a gridview based on two dropdown lists. The first list limits the values of the second dropdown list. On page load all available results are inserted into the gridview. After selection of the dropdown list, the gridview is refreshed with data limited to the two selections. This will result in 200 rows of available data. The user can select the page they want to go to using the page index.
They will then select the row to edit. Everything is fine up to here. Then the user will update the record with the appropriate data from the dropdown lists in the gridview or update the text box as necessary. They hit the update selection and the row is updated. The only problem is that they are brought back to the first page in the index. Since most of these people will be working through the list relatively in order, it would be nice if they could stay on the page they were working on rather than going back to the beginning every time. Is there a way to go back to the same pageindex they were at when they started the update?
I am including my code. I tried to use a variable for the pageindex as well as the selected values of the dropdown lists but I am quite sure I have applied them in the wrong places.
i've dynamically created new rows on button click in gridview with 3 dropdownlist.for the first default row the selectindexchanged is firing and on pageload 1st ddl is loading with values and basing on selection the second ddl is showing values and third ddl is showing basing on second ddl. Now, when i click add new row, a new row is created with 3 ddl's ...1st one is showing properly but when i select from that ddl ,it should show data accordingly but its not showing particular data but showing all realted data from DB.same for 3rd ddl.
Also when new row is added and the first ddl is selected on postback the second ddl data is refreshing..
now when i type something in header Search cell , it shows the data of first page index only , it won't show me data from 2nd page index .. here's my code :
protected void PhasesTempGrid_OnDataBound(object sender, EventArgs e){ GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal); for (int i = 0; i < PhasesTempGrid.Columns.Count - 1; i++) { TableHeaderCell cell = new TableHeaderCell(); TextBox txtSearch = new TextBox();
[Code] .....
My gridview is in update panel therefore i did this in .js script :
I m getting Problem in Tab Index Setting of Dynamic Created Controls. There are 6 Drop down dynamic created and also Two user controls which contains text boxes. There are also Static Controls on a Page. How i set tab index for all controls. I have try to give from code behind using TabIndex property But it's not working and Tab order get destory.
My purpose is to modified some data only for current page in a gridview. I call this function in page load and GridView_PageIndexChanged events. When it's called in page load event, it works fine. But when it's called in PageIndexChanged event, only the rows on the first page in GridView are looped through. For example, if I click page 5, the rowStartIndex becomes 100 = 5 x 20 (my pagesize). The if condition becomes itemsRead >= 100 andAlso itemsRead < 120. But after itemsRead is increased to 19, the For each gridViewRow loop stops and the if condition is never satisfied.
I got a web page, it has a tabcontainer, within each tab, there will be a gridview, all the tabs and gridview are created at run-time, i have only one code, that I will loop through to create all those tabs and gridview. When I apply the sorting, and I click on the column name on any grid, it returned an error saying index was out of bound. BUT, when there is only ONE grid view created, it is working fine, I suspect it mixed up all the grid view's id and so on. But I have assigned different ID to gridview
When "btnEdit" is clicked, "RowCommand" event is raised where I want to the catch row index of the row which was set to Edit mode.The Reason for doing this is ......I am using paging with page size = 4. When I click the fourth row (suppose), page is postedback and then the user has to scrolldown to get to the edit row
I have a GridView with drop down boxes that are always in edit mode, and what I want to do is when the user sets a value in one of the drop downs I want to set the value in all of the drop downs BELOW that one (if they are not currently set) to the same value. However, the RowEditing and RowUpdating events never fire because techncially I'm not editing or updating the row.
Here is what I'm wanting to do, something along these lines:
[Code]....
Here is what is corrently working, but it sets the values both above and below the current row:
it is a simple question, but i didn't understand. here is the code below:
Private Sub GridView1_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowCreated Dim drv As DataRowView If e.Row.RowType = DataControlRowType.DataRow Then For i As Integer = 0 To e.Row().Cells.Count If " ".Equals(e.Row().Cells(i).Text) Then e.Row().Cells(i).Text = "" End If Next End If End Sub
the line "If e.Row.RowType = DataControlRowType.DataRow Then" occured exception below System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection
I am getting error Specified index out of range of valid values. Parameter name index. I tried to put a breakpoint and see where am I getting the error. I have 5 columns (1 hidden). first 3 columns- no issue. But when the control reaches the 4th column it throws the error. I saw that I am getting correct values for the first 3..no ide what is going wrong with the 4th one.
Is there a way to find out which column is selected in the Gridview row command? When I click on a gridview row in a specific column, is there a way to get the column index of the selected row?
