Scenario: I have a Gridview where I want to handle the Sorting in a custom control that I've added to the header. I've added this control to my GridView's Header via OnRowCreate event handling. I want the Sort Expressions to persist session to session (via Webparts Personalization)
Here is what I have for adding the custom header control to the GridView Header
[Code]....
This works out well for adding the control, but I can't get anything to persist because these controls are creating initially via postback (per the event) and re-created on all subsequent postbacks. I can't add an If(!IsPostback) because the controls are initially created on the gridview's postback (well at least thats how it's acting when I put it in there) If I were to add this control via the ASP page, not via the Codebehind, I would be able to persist the control. If I try to treat it as though everything is setup correctly, and assign my custom control's controls to [Personalizable], I get a runtime error telling me that I can only have webpartzones in or before Page_init (I'm guessing this is due to when/where the gridview hits the OnRowCreate event). If there is some fundimental logic I'm missing, or best practices that I'm moving away from,
i have a gridview in my website and i want to merge two cell of that in same column but in different row , for example i have a data about tours in an agency , now i define a tour that has two hotel with difference grade , i want tow show my grid view in this manner :
I've created a DataTable by programming and I'v inserted a new DataRow into it, I binded it with a gridview (It's ok), but that new row has many columns, how can I merge all columns of that new row and set the value will be show of that row.
Here is my snipet:
Store1
row [Column1],[Column2],[Column3]
row [Column1],[Column2],[Column3]
Store2 (new row I've created and I want to merge all columns and show the value is Store2)
want to merge the columns into gridview example SELECT b.TableName,c.ColumnName,a.DataProfileAction,(a.ForeignTable+'/'+a.DataProfileAction) As MergeRecords From DataProfiling As a Inner Join TableList As b ON a.TableId= b.TableId Inner Join MetaDataTable As c ON a.ColumnId=c.ColumnIdquery working.. suppose if any one column empty while binding times it come as empty..
I'm working on a project in vb.net framework 2.0 and have a column that has server names. I have the accessdb sql setup to order by the db, what I would like to do is to have it look like the following picture below. I'm pretty stumped on how to do it as the methods I've found online haven't worked so well. Also just a small tid-bit the gridview is bound to a ddl which selects the application and the gridview refreshes with server data. Country would be server name and state would be the environment.
How to merge gridview columns in a grid when the items in the grid are duplicate. i mean in one row four columns are there i need to merge the columns which are repeating

I am able to display it in gridview but not in the above style, that is the columns in excel above are merged, but I have fail to merge gridview column. I have searched google for solution but what I found is that of merging row or header, but what about this one? Note, I can not fixed this style as user can upload excel routine files to server of different style.
I want to create simple rating page where player's place,name and rating is displayed. I've created database with ID,Name and Rating Columns, binded Gridview to this database and created TemplateField "Place". With following code I've created numbered list for Place:
protected void Page_Load(object sender, EventArgs e){ for (int i = 0; i < GridView1.Rows.Count; i++)
I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.
ASPX:
[Code]....
And here's the Code Behind:
[Code]....
No design time errors reported but here's the run time error:
Object reference not set to an instance of an object.
On the following line:
Line 28: if (row.RowType == DataControlRowType.DataRow)
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.

Also just a small tid-bit the gridview is bound to a ddl which selects the application and the gridview refreshes with server data. It is sorted by server than environment so the columns contain much of the same info for those over and over. Country would be server name and state would be the environment.
I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.
I have problem while set or passing value from code behind to asp:label inside gridView asp:templateField. 1st. I have gridView and using SqlDataSource control for data source. This is my gridView code?
[Code]....
2nd. I have SqlDataSource for my GridView. this is the code :
[Code]....
We can set value in the *.aspx or design view by using <%# bind("str_isi") %> like the asp:label control with ID=lblGvPengumuman but how we can set value in code behind?
i want to sort a gridview column which is a template field with a repeater control in it. this column has multiple links and i would like to sort using the first link. how can i achieve this.
Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?
