Forms Data Controls :: How To Use DataNavigateUrlFields In A GridView To Pass The Value Of TemplateField To Another Page
Nov 17, 2010
I have a GridView with a SQL DB datasource.
I am using a HyperLink Field in the GridView to pass two of the values in each row to another page using DataNavigateUrlFields.
One of those values is straight out of the DB and, if I just pass that, all is well. The other, however, needs to a simple integer (1 - 10) and I've added a TemplateField containing a DropDownList manually populated with these numbers for this purpose.
I keep getting an error saying that the DDL value is not in the DataSource.
How do I add this field/value to the DataNavigateUrlFormatString?
how to pass value in GridView from Page1.aspx to Page2.aspx
In the GridView, I add one column that have CheckBox and the GridView have 5 rows then it will be 5 CheckBox.
What I would like to do is, when we checked 3 CheckBox from the GridView and click submit button, it will go to the Page2.aspx and display back the GridView but only display 3 rows that had been checked from the Page1.aspx I'm using VB
Each row has a "View Large" link which passes the image id to another page whereupon the image is displayed in a DetailsView.
That page has a "back to album" hyperlink.
All this works nicely, however, no matter what page the user was on in the GridView, having clicked through to the DetailsView and then back to the GridView, the user ends up on page 1 of the GridView.
How can I ensure the user comes back to the same page in the GridView that they were on when they clicked through to the DetailsView? Do I need to pass the gv.PageIndex value and send it back; can I just somehow tell the GridView to "stay where it was"?
Here's the code for the GridView (it pulls the image info from a SQL db:
I want to create simple rating page where player's place,name and rating is displayed. I've created database with ID,Name and Rating Columns, binded Gridview to this database and created TemplateField "Place". With following code I've created numbered list for Place:
protected void Page_Load(object sender, EventArgs e){ for (int i = 0; i < GridView1.Rows.Count; i++)
I have a GridView, bound to a table (Meals) in a SqlDataSource.
Into that GridView, I have added a TemplateField, which contains a DropDownList (which displays the numbers 1 - 10, added manually; no Data Binding). And, I've added a ButtonField.
When I click the Button, I want the values of some of the GridView rows PLUS whatever value was selected in the DropDownList to be pulled out and stored in a second Sql table (Orders).
Pulling the rows bound to the SqlDataSource is easy but JavaScript is needed (I think) to pull the SelectedValue from the DropDownList. I understand women more than understand JavaScript (that's how little I know) and the code below has been kindly offered by another forum user who is at a loss, himself, now.
Here's the code and the error message I'm getting.

No design time errors reported but here's the run time error:
Object reference not set to an instance of an object.
On the following line:

I'm relatively new to the VS environment. I'm using VS2010 Beta 2 with VB. I have a Gridview setup to pull a list of employees. Next to their name I have edit and delete icons. When I leave the icons as ButtonFields, they pass the DataKey value to my code behind perfectly. When I convert the ButtonFields to TemplateFields, they no longer pass the DataKey.
I have problem while set or passing value from code behind to asp:label inside gridView asp:templateField. 1st. I have gridView and using SqlDataSource control for data source. This is my gridView code?

2nd. I have SqlDataSource for my GridView. this is the code :
[Code]....
We can set value in the *.aspx or design view by using <%# bind("str_isi") %> like the asp:label control with ID=lblGvPengumuman but how we can set value in code behind?
i want to sort a gridview column which is a template field with a repeater control in it. this column has multiple links and i would like to sort using the first link. how can i achieve this.
Though it is usually not a big deal to edit the source code to accomplish this, I am just curious if there is an easier way to reverse the conversion of a column to a TemplateField. The covnersion can be done by a simple click. Is there a similar click to reverse it?
i have a website with a radiobutton inside a gridview, i set the groupname in the gridview but when i run the table, the radiobutton did not became exclusive or i can checked = true on all radiobutton. this is my code:
I have a gridview with a DropDownList (contained in a TemplateField). I have set the OnSelectedIndexChanged event to a function called "ddlAgent_SelectedIndexChanged" This allows me to aquire when a user has changed the value for the dropdownlist. What I need to do is persist this newly selected value to the database for the gridview record. The problem I'm having is how to I get the datakeyNames value for that row? See code below!
Protected Sub ddlAgent_SelectedIndexChanged(ByVal sender As Object, ByVal e As System.EventArgs) Dim gvItems As DropDownList = CType(sender, DropDownList) ' Write the selected Agent ID to the Inquiry record. 'Dim ID As Integer = gvMaint.DataKeyNames(e.SelectedIndex).Value ' THIS FAILS BECAUSE e.SelectedIndex is not part of System.EventArgs End Sub
I have one two GridViews on a page. One Gridview uses BoundFields inside of the GridView and the Update statement works just fine. The other GridView utilizes TemplateFields due to the fact that Validation Expressions have to be used. I also want This GridView to be able to update the vlues when the user clicks on the Update link on the right side of the GridView. The GridView that uses the BoundFields updates just fine, but the GridView that uses TemplateFields will not update. I have checked and everything is correct other than this difference of BoundField and TemplateField.
I have a gridview and I want to have a template field. In the template field I want a word over an image. I can get the image in it's own cell with <asp:ImageField DataImageUrlField="IMAGE_URL" > </asp:ImageField>
But I don't know how to access this in a templatefield
I binded user control in gridview dynamically using templatefield (through code behind)
User control consists of 2 textboxes and one dropdown.
There is one button outside the gridview on the form. On click of that button i have to save the values of usercontrol's (child controls i.e textbox and dropdown values) but i am not able to get the values of user controls.
I am able to get User Control using LoadControl and child controls using FindControl but not able get values i am getting textbox values as blank and dropdown value as 0th selected index even though there is value entered by the user.
