View 2 RepliesI'm attempting to load a GridView dynamically on a button is pressed.The gridview has AutoGenerateColumns="True" (set in skin definition) and has a declarative column definitions as follows:
<asp:GridView runat="server"
SkinID="GridViewDetail" ID="gvReport"
DataKeyNames="dateofcompletion">
<Columns>
[code]...
This all works fine the first time, but as soon as I select a different ddlCampaign item, it throws the"A field or property with the name 'FieldName' was not found on the selected data source" ERRORI kinda understand that it has retained the column mappings from the previous datasource assignment/binding and because the new datasource has different column headings it is throwing the error. What I can't seem to achieve is a clear or reset of defined gridview columns before adding the new columns. I cannot clear all columns because part of the GV defn is declarative.e.g.
gvReport.Columns.Clear();
gvReport.AutoGenerateColumns = true;
I have also tried clearing the previously added columns before new assignment/binding but it gives the same error.e.g.
for (int i = 2; i < gvReport.Columns.Count; i++)
{
gvReport.Columns.RemoveAt(i);
}
I am trying to bind the XML data to a datagrid from an XML file. I don't know why I am getting the message: "A field or property with the name 'User_x0020_Name' was not found on the selected data source."
The "User_x0020_Name" field does exist in the XML file. This is a portion of the XML file.
<?xml version="1.0" encoding="utf-8" ?>
<DataSet xmlns="http://www.----------.com">

this is the error: A field or property with the name 'idcode' was not found on the selected data source.and what i am trying to do is this... i don't understand that. i never used DataSet before.

I know that you can use exclamation sign to bind array of simple types (like string) to GridView like this
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false">
<Columns>
<asp:BoundField HeaderText="Array Field" DataField="!" />
</Columns>
</asp:GridView>
But this doesn't seem to be the case with DataNavigateUrlFields
<asp:HyperLinkField DataNavigateUrlFields="!" DataNavigateUrlFormatString="RoleInformation.aspx?role={0}" Text="Manage users" />
and I get following error:A field or property with the name '!' was not found on the selected data source.

I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

I am displaying a table into a gridview for which I've a SQL query written which uses IF-ELSE condition. In one of the conditions, if the condition stands TRUE then one of the coloms should be eliminated from the table. But I constantly get an error:"A field or property with the name 'IXC_Vendor_Circuit_ID' was not found on the selected data source."

The question is: do I need to limit number of selected rows in data source for GridView?
When I use paging in GridView does limiting selected rows make GridView work faster?
Now I use ObjectDataSource with Linq in functions.
[Code]....
Does this make sense or I can just use LinqDataSource without thinking of selected rows?
I have a dataview on a page. I am binding a list of Items, and each item has a Person object. So I get this exception "field not found in selected datasource" when I try to bind to any property on the person object.
[Code]....
It appears that the dataview is having problems with the person object because it will display all the properties for the Item correctly.
why I get a not found on the boundfield and not on the eval?

I've got my Drop down list databound to an sql data source, now I need to change the data in a few of the fields before it gets displayed. I've been messing with this all morning and I can't find anything useful, this is what I've got so far and it's clearly not working.
Protected Sub ddlBookType_DataBound(ByVal sender As Object, ByVal e As System.EventArgs) Handles ddlBookType.DataBound

For i = 0 To ddlBookType.Items.Count - 1

ddlBookType.Items(i).Text.Replace("mod_cook", "Modern Cooking")

i have to a grid view and the datasource for it is a table coming from the database the table containing sequence numbers for example if the sequence number is 1 then i want to add a row just above this saying it is the start , the entire row should give some information .
i tried to find related thing but no luck, waiting for some replies to move further
I need to be able to get the value in the "first" row of a Gridview as its getting or right after it is displayed.
I thought this would work but its coming up null.
I'm using the DataBound event to get the value of the control of a selected row...assuming the selected row is the first row which is probably the error of my ways. Any ideas how to get at this value easily?

The Story
I've written a page outside of Visual Web Developer 2010 that uses a SqlDataSource object along with a FormView object that works perfect. Building upon those awesome skills I obtained I started to build a project within Visual Web Developer, this time creating an Empty Web Application and went along my happy way building my new site. I used the same techniques and almost the same code as before - just pointing to a different table but I was met with the aforementioned error message.
The Confusing part
Here's the puzzling part - if I take my page I wrote outside of Visual Web Developer, again - it works perfect - no complaints, and add it as a page to the project I've built it now presents the same error message and I have no idea why.
The Tests Completed
I've backed off of targeting .NET 4.0 framework and went to 2.0 as I am not using any specific 4.0 controls or methods at this time. I've taken my page that originally gave me issue and recreated it outside of a Visual Web Developer project and instead as a stand alone page and the exact same code - copy, cut, paste - works perfect!
I have two gridviews, where the first is databound to a sql table (but does not display the primary key info), and want to filter the data displayed on the second gridview by using the primary key info from the first gridview table, indicated by the selected row in the first gridview - how I could achieve this? its kind of like using the gridviews as a menu and sub menu display!

So I am uding a GridView bound to a SQL data source.
I have a template feild bound to a SQL BIT
<EditItemTemplate <asp:CheckBox ID="chkSelected" runat="server" Checked='<%# Bind("Selected") %>
The original Item Template was Enabled ="false" I changed this so that you did not have to set the row to a state of edit in order to just select a row. I enabled it so that you could "select" any row with out putting it in a state of edit. the only value changing is if its selected or not. What i am trying to do is use the Data Source Update method to update the bit in the database based on the check box. Currently Update() returns 0. I believe this is because the row/feild is not marked as changed so the Data Source does not see it as something that needs to be updated.
What I am hoping for out of this is post is a way that the rows whom check value has changed to be marked as changed/edited so that the data source will update the database with the values of the check boxes. If all rows are updated this is acceptable as well. I know this is a super simple solution but i have been out of the .NET for a little bit.
