I have 2 grids gvParent & gvChild I would like to filter gvChild when a row is selected in gvParent the linking fields are contractNo
I added a column for selecting:
<asp:TemplateField ShowHeader="False">
<ItemTemplate>
<asp:LinkButton ID="LinkButton1" runat="server" CausesValidation="False" CommandName="Select"
OnClick="LinkButton1_Click" Text="Select"></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
I know how to handle the filtering of the grid (create a criteria and set to rowfilter of the dataview) But, I dont know how to get the value of the column of the selected row.
Simply put... I want to duplicate the example found at this link, in VB.net rather than C#.

I would like the selectedvalue of the dropdown to display additional data base on its selection in multiple text boxes.
I have tried using the DropDownList OnSelectedIndexChanged property, within a DataGrid EditiItemTemplate, but I cannot retrieve data from the selection. (AutoPostBack is "True"). I can however use a button onclick event to fire a "prre-defined" selection value.
I bind custom DataTable to DataGrid through ObjectDataSource, where i use SelectMethod and UpdateMethod. SelectMethod working great, but when I try to update row it's breaking by MissingMethodException. What should i do to fix this problem?

View 7 RepliesI have a literal inside each datagrid item. When the datagrid binds I set the literal equal to a small javascript script (a third party source). It works great. when I update my update panel the javascript is lost. I know this is a known issue. From googling they recommend you use:
ScriptMananger.RegisterStartupScript
However this renders the javascript at the bottom of the page. I need it inside my datagrid items. Is there a way that I can register my javascript to my literal control?

View 3 RepliesI have an AJAX accordion from the ajax control toolkit on a page with a datagrid inside on of the panels. I have a custom itemtemplate for the one column to create a multiline textbox when I click edit on the row. When I click update on the row, the original content of the textbox gets rendered into the textbox. It is supposed to update and go back to the literal not the textbox. When I put the DataBind() into a !IsPostBack, it doesnt get rendered when I click on the accordion pane.

I'm new to ASP.NET (both the site and the platform) and am I wondered if you guys could help me figure out how to add tooltips to a DataGrid column, specifically, the HyperLinkColumn (example shown below). I'm sure there's some magical way to do this in JavaScript but a search turned up nothing.
<asp:hyperlinkcolumn headertext="File Name"
datatextfield="file_name"
datanavigateurlformatstring="../fileserver.aspx?id={0}"
datanavigateurlfield="FILE_ATTACHMENT_SEQID"
ItemStyle-Width="60%"/>

where I'm going wrong with this SQL Query of an Access Database which populates a Datagrid,
From a calendar selection the user can select a From and To Date and I want the SQL Query to ONLY pick up the dates between these two values, the selection is fine it seems to be the sql query which is the problem ... (I have added dates rather than the text value to make it easier to get working ) the following query wil pick up dates outside of the selected values 01/08/2010 , 02/08/2010, etc
SELECT COUNT(*) AS Date_Installed, Date_Installed AS Expr1, Installed_By FROM Buildprocess WHERE (Date_Installed BETWEEN '20/08/2010' AND ' 25/08/2010') GROUP BY Date_Installed, Installed_By
ASCX File:
<asp:datagrid runat="server" id="gridFormFields" datakeyfield="FieldID"
autogeneratecolumns="False"
onitemcommand="gridFormFields_ItemCommand" onitemdatabound="gridFormFields_ItemDataBound">
<columns>

View 3 RepliesI have a usercontrol with a datagrid that is used throughout my web application. The datasource is passed in a public method from the master page to this usercontrol, as the data selection is different on each page where this usercontrol is used.But by doing this, I'm having a problem with paging, as the datasource is lost after postback. I can't do the data selection in the usercontrol itself as the dataset is passed as a parameter.
