When a gridview is rendered, its RowCreated event is called. When it is called, what is contained in the second parameter which is of type System.Web.UI.WebControls.GridViewRowEventArgs ?Means, which type of information can we get from that ?

[Code]....
Knowing that AssetClass is an Enum:

The 1st time I submit the form everything is working well, the second time theGridView1_RowCreated fires an exception when the property AssetClass is called. The error message isMust specify valid information for parsing in the string. This is becauserblAssetClass.SelectedValue is empty, but I don't uderstand why.

View 3 RepliesI have a gridview with some text-box columns and one dropdownlist-column (Templatefield).
With the dropdownlist i wan't to be able to edit a cell in a row. I have read a lot on the web and i have folowing code. I only get a parameter error now, before i added the dropdownlist everything was ok.
This is my html:
[Code]....
This is my update-command in the class "TransactiesDAO"
[Code]....
Look at the line:
[Code]....
in the aspx code. I don't now what to type in the "Bind(...)" text.
With above i get error: Message=DataBinding: 'System.Data.DataRowView' does not contain a property with the name 'Subrubriek'. when trying to update the row.
When i delete the line "SelectedValue=" then i get folowing error:
It gives me folowing error:
ObjectDataSource
'ObjectDataSource1' could not find a non-generic method 'UpdateTransactie' that
has parameters: Rekening, Omschrijving1, Omschrijving2, Boekdatum, BedragBij,
BedragAf, Subrubriek, @ID_SR, ID
I have a cell where I will display an url with an xml as parameter. Currently this shops of the Gridview dispaly, the html table that is generated can not correctly be read by the browser.
Do I have to encode my string, the HTML encode mehtod? Or do some other action?
I am defininging all my sqldatasource select parameters upfront in the .aspx file. Then based on user filter choices, I modify the Select Command to include those parameters. Works fine, but when I add one of these parameters, the bound grid doesn't pull back any results. No error message is given.
If I remove the ToteID control parameter line below, everything works fine. But with it in, the SQLDataSource.Selecting event doesn't even fire.

My database has 4 colums;
TraditionalID-------------TraditionalName------------Singles-----------Suppers
Singles and suppers are money fields for the price of same item. A bit like the price of a Small, Medium or Large item. What I would like to do is display the 'Singles' price and 'Suppers' price in seperate listitems so the user can choose 1 of them.
GridView:
Traditional Name__________Size
Chicken-------------------[DROPDOWNLIST]
DropDownList:
Price of Single is: £1.50
Price of Supper is: £2.50
My page loads up with the correct items in TraditionalName colum but the DropDownList is completely empty. I'm aware I don't have anything in for DataValueField and DataTextField but I have tried putting things in these attributes, like Suppers and Singles, but nothing works, so I have taken them out below.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" DataKeyNames="TraditionalID" DataSourceID="SqlDataSource1">
<Columns>
<asp:BoundField DataField="TraditionalID" HeaderText="TraditionalID" InsertVisible="False" ReadOnly="True" SortExpression="TraditionalID" Visible="False" />
<asp:BoundField DataField="TraditionalName" HeaderText="Meal" SortExpression="TraditionalName" />
<asp:templateField HeaderText="Size">
<ItemTemplate>
<asp:DropDownList ID="DropDownList1" runat="server" DataSourceID="SqlDataSource2">
</asp:DropDownList>
<asp:HiddenField ID="RowTraditionalName" runat="server" Visible="false" Value='<%# Eval("TraditionalName") %>' />

ConnectionString="<%$ ConnectionStrings:The CodfatherConnectionString %>"
SelectCommand="SELECT Suppers AS Suppers, Singles AS Singles FROM [Traditional] WHERE TraditionalName = @TraditionalName">

during edit mode i populate the drop down in question with data based on a value selected in another drop down also in the gridview, all works find, but the paramater is not being updated with the selected value, i think this is because i do not call any Bind in the aspx side.
<asp:TemplateField HeaderText="Build Types">
<ItemTemplate>
<asp:Label ID="lblBuildTypes runat="server" Text='<%# Bind("BuildType") %>'></asp:Label>

I have two image buttons in a gridview, one to approve the opening of the record and one to approve the closing of the record. I have added a CommandName to each button (OpenApproved and CloseApproved) and in the grids rowcommand I would like to update the database with the Username of the person clicking the button, Username goes into either the OpenLeadApprover or CloseLeadApprover field depending on which button is pressed. The grid has a sqldatasource with an Update stored procedure which has three parameters, @WorkOrderIDWhat I have tried to do in the RoeCommand event is declare a variable for the sqldatasource and add the parameter value to it, then run the update command. Here is the code:

Basically, the user Selects a row on GV that executes an Insert into a table the GV cell values of the selected row.
The SQL field data type is varchar. If the GV field is Null, the Insert adds the value to the SQL field. How do I keep the @nbsp; from being displayed in the cell of a data control when it is called at a later time? Do I add some more asp to my control parameter? do I add some vb code behind? Here are some relevant code snippets of existing code.

I have 2 dropdownlist(ddlCategoryFooter and ddlItemCodeFooter)inside my gridview. I want to set ddlItemCodeFooter 's datasource to my getItemList(decimal categoryID) method. The selecteditem of ddlCategoryFooter will serve as the paramter which will be passed to my getItemList Method. Basically,ddlItemCodeFooter is dependent on ddlCategoryFooter's selectedItem.
I know it can be done in code behind approach but i prefer to place it in my asp page.
This i what i want to acheive:
DataSource ='<%# getItemList(Convert.ToDecimcal(ddlCategoryFooter.seletectItem))%>'/>

Forms Data Controls :: Failed to convert parameter value from a DataControlFieldCell to a String - GridView Error?
I have a dropdownlist outside the gridview control. My griview control also have dropdownlist in the first column. I want to populate the dropdownlist inside the gridview control for all rows when the selected item is changed in the outside dropdownlist.
View 2 RepliesI have a SQL table containing a timestamp column. This table is displayed in ASP using GridView control. The timestamp column is indicated in the DataKeyNames property of the GridView. I'm using TemplateFields for all columns and a ItemTemplate HiddenField control connected to the timestamp column using Eval.
<asp:TemplateField
ItemStyle-Wrap="false"
Visible="false"
HeaderText="timestamp"
SortExpression="timestamp">
<ItemTemplate>
<asp:HiddenField
ID="gv_hid_timestamp"
runat="server"
Value='<%#
Eval("timestamp") %>'
></asp:HiddenField>
</ItemTemplate>
</asp:TemplateField>
The data is displayed properly. I'm trying implement the optimistic concurrency in C# using the value of above mentioned timestamp and a stored procedure. The SQL stored procedure expects the @timestamp as varbinary(8). I'm not sure how to pass the value of gv_hid_timestamp back to the stored procedure. I'm using the following:
command.Parameters.Add("@timestamp", SqlDbType.Binary).Value = Byte.Parse(((HiddenField)gv.Rows[row].FindControl("gv_hid_timestamp")).Value);
resulting in the following error: "Input string was not in correct format." (I also tried different data types but with similar result). I want to be able to pass this parameter programmatically from C# and not have to specify it on the UpdateParameters list.
in my asp.net+access web code in vb. There is three labels named (tata.text,tvs.text,msu.text) is there any option on clicking on the label named tata.text the data pertaining to tata be displayed in a gridview in another page or a popup display in same page.
View 1 RepliesHow do you use the http POST method with a Grid View on another page. I am trying to use the POST method to send the ID from the selected row of a Grid View, I am using a link button set to fire the select command and it has the Post Back URL set, from one page and then retrieve the ID value on another page using an Object Data Source. Also, under the Defining Parameters, I am setting the ID parameter to Form Parameter Source and have entered the Grid Views name in the Form Field.
