Oracle Error When Selecting From Gridview That Is Bound To Another Gridview?
Oct 23, 2010
I've been working on a webform to pull data from an oracle database v10. I can create a gridview1 with Selection enabled and it will populate with data without a problem. However when I create a second gridview and bind with a control to the first gridview, I get the following error at runtime when I click on one of the Selects.

The first page show up just fine, when i try to go to the second page of the GV i get this errorThe GridView 'GVCreditMemos' fired event PageIndexChanging which wasn't handled.
I have designed a gridview one of the fields of which I want to send the user to an URL onclick. After browsing the net for a while, I opted for converting the BoundField to a TemplateField. The same OLAP metric ([Measures].[GP]) works fine in the bound field yet produces an error in the Template:
I have a simple gridview control. It has edit and cancel buttons for each row. User's can click on edit column and edit a row and click on save to save the record.
When the user clicks on save we get the error: ORA-01008: not all variables bound
User is allowed to edit only 3 fields and rest of the fields are only readonly. For those editable three fields, I am using EditItemTemplate. ASP.net doesn't throw any errors for the first two edititemtemplates. The problem comes only with the third field which is "BSIS Type". I tried to figure out almost 5 hours and don't know what to do.
This the code I have:
HTML Code: <asp:GridView ID="GridViewActualsMapping" runat="server" HeaderStyle-BackColor="#444444" HeaderStyle-ForeColor="White" Font-Size="10pt" Cellpadding="4" AutoGenerateColumns="False"
[code]....
Error is:
HTML Code:
ORA-01008: not all variables bound

If the gridview binds to empty dataset, I need to still show a gridview so that users can ADD more using the textfields in the bottom of the footer template. Since the gridview is empty it won't bind not allowing rendering of the <footer template> I guess I should create a empty dataset if the gridview is empty. How do I check for this and can this be done in GridviewRowEventArgs
I am listing details using a gridview and wish to just display the first 50 characters of a 1000 character field. I feel this should be simple but cannot find the solution.
I'm having some evils trying to get my GridView control to behave. I have the below code, which successfully displays all the files in the directory. However I require two changes, both of which I am struggling with:
a) Currently the URL you get when clicking on the URL field is [URL] (ie my home directory with the filename). What I require is that the 'Display Text' be the filename only, and the URL be my desired text followed by the filename eg: [URL]
b) I want only to see the files that start with a certain prefix eg "Pay". I can do that with something like: string[] filelist = Directory.GetFiles((@"C:MFData","Pay*.*"); but this doesn't like to bind to my Gridview!
const string DocumentFolderPhysicalPath = (@"C:MFData"); const string DocumentFolderUrl = (@"C:MFData"); [URL]; ; // now it is hardcoded but you could retreive it automatically HyperLinkField hyperLinkField = new HyperLinkField(); hyperLinkField.DataTextField = "Name"; hyperLinkField.DataNavigateUrlFields = new string[] { "Name" }; //Would like this to work! //HyperLinkField hyperLinkField2 = new HyperLinkField(); //hyperLinkField2.DataTextField = "Destination"; //hyperLinkField2.DataNavigateUrlFields = new string[] { (@"C:MFData") + "Name" }; GridView1.DataSource = GetDocuments(DocumentFolderPhysicalPath); GridView1.Columns.Add(hyperLinkField); GridView1.DataBind();
private System.IO.FileInfo[] GetDocuments(string physicalPath) { System.IO.DirectoryInfo directory = new System.IO.DirectoryInfo(physicalPath); if (directory.Exists) { return directory.GetFiles(); } else { throw new System.IO.DirectoryNotFoundException(physicalPath); } }
I have a repository that contains all of my LINQ queries for this project that I am working on. I am able to get the LINQ results to a DataTable and bind that to a gridview for displaying the data. Now I need to make the gridview sortable. I have set AllowSorting="true" and I have the OnSort event handled in a routine in the codebehind.
from my collection entity I am getting DayOfTheWeek like 1,2...7. 1 for monday , 2 for tuesday like that. Where should I place condition so that in grid view it would display day name rather than corresponding code.
My GridView is bound to a certain DataSource. Each row only shows 4 of the 8 possible items. Lets say we have name, adress, phone, fax, email, country, province and age. The GridView would only show name, email, country and age, but I want to access the province and adress bound to a row.
I got a custom GridView, with an onclick event which updates an panel (through AJAX) which shows additional information about the selected row.
I have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.
I have an aspx page with 2 controls on it - a GridView bound to a SqlDataSource control.Am I correct in thinking this is 2-tier ?If I were to replace the SqlDataSource with an ObjectDataSource, and make the database connections/calls/queries via a class in the App_Code folder, this would be 3-tier, right ?
I have to set maximum length for bound field in an editable gridview. For this i have used data format string property and also given ApplyFormatInEditMode="true" still it accepts invalid input. The gridview does not have template field, it contains bound fields only. I have written OnRowEditing and RowUpdating events. The dataformat string is DataFormatString="{0:N0}" but it accepts '2352345234523454352345' input also and displays server error while updating in database. I want to spcify maximum length for the textboxes generated dynamically when Edit button is clicked.
I have a gridview which is bound to a DataTable. When I try to sort the gridview, it goes blank. How can I enable sorting this gridview? I know this question has been asked before, but what I'm looking for is an explanation of how to do it. Perhaps with a simple example.
I have read that I need to put some code in the on_sorting and/or on_sorted events, but I don't understand what needs to go there. Again, I want to understand the method of accomplishing this, I don't just want a giant block of code.
i think this maybe an easy one...I have a Gridview, bound to a dataSource with this query:select userid, name, phone from usersI need to change the content of the Name cell to a link, like so:<a href="http://www.domain.com/page.aspx?userid=12345">User's Name</a> so OnRowDataBound i'm doing this:
It all works fine this way. My problem is that i don't want to display the UserId column in the Gridview, but when i attribute it (asp attribute or server-side) Visible="false" to the BoundField UserId, i can't capture it's value to build the Name Cell.
I'm hacking my way through ASP.Net WebForms, coming from VB.Net WinForms. I was hoping the transition would've been more seamless... it is not.
I have a GridView (Paging enabled) bound to a DataTable, filled with Joined tables from an Access 2000 DataBase.
The GridView and DetailsView are bound to the same DataTable.
In the GridView's SelectedIndexChanged Event I have the following:
vb.net Code:
' dtvSelected is the DetailsView' dgvJobTOF is the GridView Me.dtvSelected.PageIndex = Me.dgvJobTOF.SelectedIndex
When the page loads the first item in the GridView is also displayed in the DetailsView.
I've added a "Select" button in the GridView and when it is clicked the Data in the DetailsView remains the same regardless of the selected GridView row.
I am trying to populate an (editable) gridview in ASP.NET with a table from SQL. I have a SQLDataSource set up for this. I also need to have this gridview be filterable based on parameters entered in textboxes. I have tried using ControlParameters for this and it works but the problem there is when all textboxes are empty I want it to display all results in the gridview. What it does is display nothing because no entries have parameters that equal "". Is there an easy way to do this that I am missing or is there a better way to go about it other than a SQLDataSource?
