unable to access some grid data

[threeo]

anyone know why.....

i have a grid on a page which has 3 colums and looks like this:

EDIT | 25067 | 78655
EDIT | 19876 | 23478
EDIT | 78545 | 87554

when i attempt to access the data from the grid like:

ogrid.Items(0).Cells(1).Text i get "25067"

which is what i would expect.

but for some reason i can NOT access the data in the last column...

ogrid.Items(0).Cells(2).Text i get ""

in fact, all column 3 items come out as ""

ogrid.Items(0).Cells(2).Text i get ""
ogrid.Items(1).Cells(2).Text i get ""
ogrid.Items(2).Cells(2).Text i get ""

anyone know why???

Is that colum a template column?

 

[threeo]

yes

 

[jbenson001]

You have to do a findcontrol to get the value:

   oGrid.Items(0).Cells(2).FindControl(control name).Text

actually....
i can't seem to get it to work.....

here's how it's set up:

<asp:TemplateColumn HeaderText="Value" ItemStyle-HorizontalAlign="Right">
<ItemTemplate>
<%# Container.DataItem("AttributeValue") %>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox Columns="20" id="txtAttributeValue" dir=rtl Font-Name="Tahoma" Font-Size="9pt" ForeColor="#006699" runat="server" Text='<%# Container.DataItem("AttributeValue") %>' />
</EditItemTemplate>
</asp:TemplateColumn>

i can't seem to be able to do a findcontrol on the ItemTemplate as it has no ID and when i try to assign it an ID it fails.

oGrid.Items(0).Cells(2).FindControl("txtAttributeValue").Text

doesn't work?

 

[threeo]

when i try that....
i get the error "text" is not a member of "control"

in fact...if you type all the way the final "."
the drop down choices don't include "text"

 

[jbenson001]

Try:

 CType(oGrid.Items(0).Cells(2).FindControl("txtAttributeValue"), TextBox).Text()

 

[Juice05]

I haven't tested this but:

Dim Attribute As String = CType(oGrid.Items(0).Cells(2).FindControl("txtAttributeValue"), TextBox).Text

 

[threeo]

?CType(oGrid.Items(0).Cells(2).FindControl("txtAttributeValue"), TextBox).Text()

Referenced object has a value of 'Nothing'.

 

[jbenson001]

You have to convert it to C#, the examples were in VB.

some value = ((TextBox)(dgTest.Items(0).Cells(2).FindControl("txtAttributeValue"))).Text();

 

[threeo]

i can't get it to work.

i think the main problem is this:
Referenced object has a value of 'Nothing'.

it just doesn't know what

oGridAttributes.Items(0).Cells(2).FindControl("txtAttributeValue")

is

i don't know why

just can't get the syntax for it

 

[threeo]

for example,

even doing this:

?oGridAttributes.Items(0).Cells(2).FindControl("txtAttributeValue").Parent

yields:
Referenced object 'FindControl' has a value of 'Nothing'.

 

[jbenson001]

what is oGridAttributtes.. I thought it was oGrid? where are you placing this code?

 

[threeo]

Dim oGridAttributes As DataGrid = CType(oRow.FindControl("dgAttributes"), DataGrid)

oGridAttributes is the name of the grid i'm trying to address....

actually i'm not sure why the above code works but when i do:

?ogridattributes.Items(0).Cells(1).Text

i get the right response:
"UserID"

 

[jbenson001]

What and where is the code to get the value?
YOu have to create a variable of datagriditem as some point in order to refernce the value.

Please post your original code used to get the values.

 

[threeo]

before i was going to do any coding into the application, i first ran the application and put a break at the point where i was going to need to access the data.

then....i switched to the immediate window to do a pre-development of the code as i was uncertain how to access the data and was going to try and see if i could figure it out. so far....i haven't been able to figure out how to address the last column of data in the datagrid. the column is a template column. it has an id. yet the findcontrol can not locate it.

this works:
?ogridattributes.Items(0).Cells(1).Text

(yields:"UserID")
but trying to access the very next column doesn't work:

?ogridattributes.Items(0).Cells(2).Text

(yeilds:"")

since it is a template column we were trying to figure out a way to use 'FindControl' but it also wasn't working:

?CType(oGridAttributes.Items(0).Cells(2).FindControl("txtAttributeValue"), TextBox).Text()

(yields:Referenced object has a value of 'Nothing')

that's where i stand right now.

i believe this is the source of my problem....

my grid is rendered as:

<Columns>
<asp:EditCommandColumn EditText="Edit"
Text="Cancel" UpdateText="Update" />
<asp:BoundColumn DataField="RequiredText"
ReadOnly="True"
HeaderText="Attribute">
</asp:BoundColumn>
<asp:TemplateColumn
HeaderText="Value"
ItemStyle-HorizontalAlign="Right">
<ItemTemplate>
<%# Container.DataItem("AttributeValue") %>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox Columns="20"
id="txtAttributeValue"
dir=rtl
Font-Name="Tahoma"
Font-Size="9pt"
ForeColor="#006699"
runat="server"
Text='<%# Container.DataItem("AttributeValue") %>' />
</EditItemTemplate>
</asp:TemplateColumn>
</Columns>

my problem is.....
i am trying to get the value in the column before the user clicks "edit" and the edittemplate takes over.
the regular template has no ID - and i can't figure out how to give it an ID like the edit template has. so....i can't address the cell in the grid.

any ideas?
