Forms Data Controls :: Unable To Get Value In GridView1.Columns.Count?
Feb 20, 2010
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

When a user submits the query to SQL when clicking a button I need to get a count of the number of rows that are returned. Which event does the gridview.count code need to be place in?
Right now I have it in the btn_click event, but in order to get it to count the rows you have to hit the button twice since the query is not returned yet. Here is my code.
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 am trying to add dynamically gridview (headerstylewidth, back-color, height, etc…, itemstyle width, back-color, height, etc…), in codebehind but I am receiving this error:
Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
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 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 GRID VIEW IN asp.net + VB Code. There is a drop down list and the selected data is displayed in web page. I placed a label in web page and code behind i used following code.
Protected Sub GridView1_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles GridView1.DataBound Label1.Text = GridView1.Rows.Count.ToString() Dim ONYO As Integer = 0 Dim DONE As Integer = 0 For i As Integer = 0 To GridView1.Rows.Count - 1 If GridView1.Rows(i).Cells(0).Text = "ON YO" Then
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
