Forms Data Controls :: GridView1 And Run The SQL Command
Mar 7, 2011
I started a C# web project in Visual Web Developer. I dropped a grid view in with designer and connected to my remote SQL database with the designer dialog based wizard. All is well there. I have in my program also a textbox where a user enters a zip code and clicks a button 'search'. When the user clicks search I want to run the SQL command "select * from flat_list where zipcode='userszipcode'". In other words the userszipcode is dynamic and different every time. It is my understanding I should use a SQLDataSource object but I do not know how.
I'm creating a confirm delete like popup with an iframe to use along with a gridview. When you click delete on a gridview row, the iframe shows up and asks if you would like to delete the associated image as well from the server. It works perfectly the first time I delete a row. After that whenever I click select or edit on a new row, it calls the rowdeleting event from the last deleted entry every time. I'm stumped.Here's the Sub:
'// Event that Occurs when the Delete Button is Clicked //' Protected Sub Confirm_Delete(ByVal sender As Object, ByVal e As GridViewDeleteEventArgs) Handles GridView1.RowDeleting Dim file_name As Array = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "/") If file_name.getLength(0) = 1 Then file_name = Split(GridView1.Rows.Item(e.rowIndex).Cells.Item(10).Text, "") End If Dim fn As String = file_name(file_name.getLength(0) -1) fn = replace(fn, ",", "%2C") fn = replace(fn, " ", "%20") Dim url As String = Me.Master.get_root_url & "CrimeBulletinProject/ConfirmDelete.asp?img_list=" & fn & "~!" confirm_delete_frame.Attributes.Add("src", url) confirm_delete_frame.Attributes.Add("style", "display: block; left: 50%") End Sub
i'm trying to issue a select command in my app soi could execute the command and retrive the data into a string variable.the problem is that this command is overloaded with DataSourceSelectArgument and i can't figure out what it is.i'm using sql server express and when issue a n insert command for example sq.Insert(); i have no problems.this the command that's holding me:
SqlDataSource sq = new SqlDataSource(); sq.ConnectionString = ConfigurationManager.ConnectionStrings["CustomerDatabaseConnectionString1"].ToString(); sq.SelectCommandType = SqlDataSourceCommandType.Text; sq.SelectCommand = "SELECT * FROM CustomerTable where customerID = 1"; string result = sq.Select(some overload that's stopping me);
I have a gridview1 with a Select column, which has a SqlDataSource that executes a Store Procedure.
I also have another gridview2, which also has its own SqlDataSource, but in this case, the Store Procedure has a parameter. This DataSource assigns as parameter the gridview1 control, and its PropertyName is SelectedValue. How can I load the gridview2 when gridview1 is clicked in the Select Column?
I have a dropdownlist (ddlList) in gridview1. I need to reference that ddlList as my ControlID for the parameter.
I tried to define gridview1.ddlList, but this did not work. Is there any way (non-codebehind) that I can use to reference a dropdownlist which resides in gridview1 from gridview2?
I have a default.aspx page which has two gridview controls i.e. Gridview1 [Displaying Order table] and Gridview2 [displaying OrderDetails table], when I am deleting a row in GridView1, GridView2 should also update its datasource because of referential integrity constraints.
Following is what I am trying to do in GridView2_Load event:
I am Just Filling My GridView using OleDb Control from Excel Sheet. and When I want to Save that I must have to Go through the Number of Columns to read at the End of Record.
I am Using
Dim Rows As Integer = GridView1.Rows.Count Dim column As Integer= GridView1.Columns.Count msgbox(Column) '--> Here I am Getting Value Zero for i=0 to Rows-1 Fori=0 to Column-1 'Work to Perform Next Next
I am using ASPNET2008 with VB Scripting and not C# Scripting I am encountering new problem.
On the WebFrm1, I just don't know how to write the coding to retrieve the CUSTOMERID data in order to retrieve the details from SQL SERVER table to fill the textbox controls.Here is the decription of the GRIDVIEW column
In the GRIDVIEW1 on the left edge one of the column is SELECT button which let the userclick on it to select the specific CUSTOMERID on the column next to it on the right.
I have a gridview code behind like below, and in the aspx page I called it <%# Eval("TrackedUsername") %> which displays a cell for me that has the username. Now, in my code behind, I want to be able to retrieve that data (username) from that gridview1, how can I do that?
I am working on a project and I need to use Master/Details view, the problem is everything works fine except when I place the Master (gridview) and Details(FromView) in different content holder.
The error I get is:
Could not find control 'GridView1' in ControlParameter 'ID'.
Description:
An unhandled exception occurred during the execution of the current web request. review the stack trace for more information about the error and where it originated in the code.
Exception Details: System.InvalidOperationException: Could not find control 'GridView1' in ControlParameter 'ID'.
I have 2 Gridviews of the same structure and header. I want when user click hear of Gridview 1 for sorting, the same sorting applies to Gridview2 onclick.
I have a problem to write a string to a LinkButton that is located inside a GridView1. Now the hiarchy of controls is like this to understand how to Find this control:
TabContainer0 TabPanel5 TabContainer1 TabPanel7 Panel8 GridView1 LinkButton1 So LinkButton1 that we want to write a string to is located in a GridView1 which is located in Panel8 which is located in TabPanel7 that is located in TabContainer1 that is located in TapPanel5 that is located in TabContainer0.
So below is my code but no string is written to that linkButton, so I wonder if I miss something basic out here?
I'm working on two gridviews , each one binded to an sqldatasource object,when I want to modify the 2nd gridview (DataSource=DataTable) an error fired !Both DataSource and DataSourceID are defined on 'GridView1'. Remove one definition.
I have a Gridview, lets call it GVDistinctDate which displays Distinct Date in one column only. For example: I got 5 rows, and 1 column where the column only display distinct dates such as 02/04/2010 | 03/04/2010 | 04/04/2010 | 05/04/2010 | 06/04/2010 where obviously this dates come from a table in the database.
Now i want to take those dates in GVDistinctDate and assign it to another gridview, lets call it GVReport, as column Header Text. For this GVReport, the first column would be StudentID where a list of studentid will be displayed, and then starting from the second column onwards, where the Header Text would be the dates from GVDistinctDate, will display a Status of absent or present according to the studentID and the corresponding date. How do it get the dates from GVDistinctDate into the column Header Text of GVReport?
AND how do it display the Present or Absent status based on the studentID in column 1 GVReport and the dates on the Header Text? Below are the codes of how i got the distinct date into GVDistinctDate
[Code]....
The code below is for GVReport and the comments are where i tried to put in the dates into the column header text.
[Code]....
There is a problem here: GVReport.Columns(k).HeaderText = headerText Error:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
I can't figure out what I"m doing wrong.. I followed this sample online at http://www.4guysfromrolla.com/articles/091102-1.aspx to include a gridview in an email. But, it keeps throwing this error.. 'GridView' must be placed inside a form tag with runat=server.I've verified that the gridview is in a form, and there are no template fields in the gridview. Heres the gridview on my asp.net page..
how would i do my Gridview delete command like a update command?
im using a datasource... and my delete command is like my update command... so i can change the status into "INACTIVE"...
DeleteCommand="UPDATE ACCOUNT_MAINTENANCE SET am_status = 'INACTIVE' WHERE (accmain_no = @accmain_no)"
UpdateCommand="UPDATE [ACCOUNT_MAINTENANCE] SET [account_type] = UPPER(@account_type), [min_deposit] = @min_deposit, [min_capital] = @min_capital WHERE [accmain_no] = @accmain_no"
when i press my delete command at gridview... the status changed into "INACTIVE" but when i refresh or press f5... it automatically update the status into "INACTIVE" also...
i have gridview in page and i want user see gridview2 to click on special data in column1 and user see gridview3 to click on special data in column2(gridview2 or gridview3 in everytime)

(I want to display nested gridview in GridView1 but GridView2 Or gridView3 by clicking on Column1 or column2)
