Forms Data Controls :: Cannot Get Values For The Cells Of The Grid
Jun 28, 2010
During rowdatabound event I am getting values for rowcount in debug mode but I am not getting values for the cells of the grid. But After rendering I am getting values for the grid in the browser. I am not using codebehind for databind() to the grid. Here is the code.
I am working on ASP.NET 4.0 application.I want to bind the data in a datatable to a grid control and i want to do some formatting. I want to merge the cells or hide the cell border in the first three columns (Merge every 5 cells in a column). And Vertical align the text to center. Also i need row border at the end of every 5 rows.
For example, If i am binding 10 rows to the Grid i need row border only at the end of 5th and 10th row. And merge every five cells only in the first three columns. All the other columns should not be changed. I also want to change the background color of the cells in all rows based on the value in that cell. How to achieve this in ASP.NET 4.0 and which control can be used to display in this format?
And in a submit button click event,I am writting the following code:ut,the problem is:I am gettting null for ChannelNumber,ServiceID,TransponderID,NetworkID,i.e.,not being able to access the values entered in those respective textboxes.Where am I going wrong?Do I need to write the same code in diff event?or diff code in diff event
i am using a gridview in my web page,i used to bind the database records to the gridview..my columns are name,empid,company name,pl leave,sl leave,total leave taken here total leave taken is not a database fields,in the page i want to fill the records once loaded pl leave and sl leave is added and display in the total leave taken column..it working properly when all pl ans sl columns fill with numbers,if some pl and sl leave having blank values.it showing an error like input sting was not in correct format..this is my code
I have a gridview in a page, and some Texboxes along with a button(for issuing a command) in the same page. The TextBoxs were inputted values and the values could be assigned to the selected row of the gridview, some fields are the same values along the rows, and the values are inputted in the TextBoxes for using several times without change.
Well, I need to know: how can I assign the values of the TextBoxes to the selected row of the gridview. in another words, how can I access the cell members of the gridview when it is in edit mode? (Q1)
If the row is not selected, I have no way to know which row should be assigned values, since there is no such things like "current row".
So, if the selecting button(or link) of the gridview is not selected, the button along with the TextBoxes should keep disabled, until a row's "Edit" button is clicked. (Q2: How can I find if the Edit button is clicked? I guess I can use the property "mode" of the gridview to indicate the situation. )
And the last question is (Q3), how can I ensure the values are updated to the database? Maybe I dont need to do more things than just click the uppdate button of the row of the gridview.
I have Parent/Child Grid (also called Nested Grids).
Parent Grid (PG) :: PG has two template fields. 1st template field has "Category ID" and 2nd template has Child Grid
Child Grid (CG) :: CG is populated in PG's RowDataBund event based on "Category ID". In CG's DataBound event, I am doing something which I need to display in CG's footer row.
Problem :: In the footer row of each CG, I have to show the "Category ID" which is in PG' row. How can I get hold of the PG's row which hascurrent nested grid (there will 'n' child grids, one for each 'Category ID' in the PG ) so I can read the "Category ID"
I was thinking if I could do something (DataBound event of CG) like this..
string catId = ChildGrid.Parent[get the index of the current row in PG].Cells[0].Text;
I want to get Row Fields in Gridview on Checkbox Change inside gridview.I have checkbox column in grid, i want to get row details in msgbox as i select checkbox. On selected index change of checkbox inside ridview.Everytime i select checkbox, it gives msgbox for row details.
I have 2 columns (name and address) in a gridview which are defined as linked buttons. Now when i click on a record in the first row (name) i am able to pass that value (selected name) to another page with rowcommand. Now i am trying to click on the second row (address) on a record but am not able to pass that value to the second page. Don't actually know how to define this in the code below. The first row (name) has to redirect to one page (this what i have already accomplished) and the second row (address) has to redirect to another page
<asp:TemplateField HeaderText="Name"> <ItemTemplate> <asp:LinkButton ID="LnkBtnName" runat="server" CommandArgument='<%# Container.DataItem("Name") %>' Text='<%# Eval("Name") %>' CommandName="go" >LinkButton</asp:LinkButton> </ItemTemplate> </asp:TemplateField> <asp:TemplateField HeaderText="Address"> <ItemTemplate> <asp:LinkButton ID="LnkBtnAddress" runat="server" CommandArgument='<%# Container.DataItem("Address") %>' Text='<%# Eval("Address") %>' CommandName="go" >LinkButton</asp:LinkButton> </ItemTemplate> </asp:TemplateField> Protected Sub GridView_RowCommand(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewCommandEventArgs) Handles GridView.RowCommand Dim strName As String = CType(e.CommandArgument, String) Response.Redirect(String.Format("Test.aspx?id={0}", strName, False)) End Sub
CODE ON PAGE II:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load LblName.Text = Request.QueryString("id") End Sub
I have a grid view and I added edit and Save buttons to it. When I click on edit I am able to edit the data but when I click on save I amgetting the data before edit.
Please see my code below.
Eg: I have start date as 2005-10-10 12:00 AM so After I click On edit it is letting me to edit, So If I edit the start date to 2010-10-10 12:00 PM and click on the save button I am stil getting the old start date. which is 2005-10-10 12:00 AM instead of 2010-10-10 12:00 PM
I have a GridView control that has a SQLDataSource.
The GridView provides me with a list of musical artists (from the tblArtists)
In the Grid, I have a field, FKGenreID, that is a Foreign Key value for music Genres.
(An example of the data in that field would be "7", which upon lookup would mean Classical in the tblGenreList table.)
What I'd like to do is add a DropDownList control that looks up the tblGenreList table and populates the DropDownList with the ID and Description from the tblGenreList Lookup table.
Now the tricky part is that if the GridView field (FKGenreID) has a value, then I'd like the corresponding Genre Description to be displayed in the DropDownList
Alternately, if there is no value for FKGenreID in the GridView, then I'd like the DropDownList to show that nothing was selected, but have the list of Genres available.
Most importantly here, when the user makes a selection, I'd like the GenreID (from the DropDownList) to be entered into the FKGenreID field in the GridView field.
My thought is that a gridview record may or may not have a value in the FKGenreID field. Either way, the DropDownList is bound to that field. The DropDownList would display a list ofGenre Descriptions for the user to select from. Upon selection, the GenreID column of the DropDownList becomes the value in for the FKGenreID field in the GridView.
Is this possible?
In case it matters, I'm using ASP.NET 4, Visual Studio 2010, and coding in VB
I have a grid view and I am unable to get the values that I edited from the grid view using below code. Can Any one look into it and advise what is wrong with my code?
