Yes.I just gave you an example.
Look at this code
int Count=1;
foreach (DataRow row in dataSetselectactivities.Tables[0].Rows)
{
string textboxValue= ((TextBox)this.Page.FindControl("txt_" + Count.ToString())).Text;
Count+=1;
}
by using above code, you can get all textbox value

is there any other possible way to bindgrid other than datasource = dataset;
datasource = datatable; datasource = arraylist; and any other
Bharani

What you are trying to do?
EVEN THE WORD IMPOSSIBLE SAYS I M POSSIBLE.
|
|
|
|
|
Yes ofcourse you can.
We can bind collections, such as Arraylists, Generic collections ie: anything that implements IEnumberable such as List<employee> and also DataTables, DataSets, can be directly assigned to the DataSource property of Data Controls such as GridViews, DataLists.
Thx,
Gayani

Hi
i have a form which has only employee number textbox and button when the user enter employee number it search the employee number from database and if the employee is found it must display employee details to another form which has all textboxes like names,surname,regionname.etc.I have search functionality which only works if i use one form so i must use two forms one for search and one for displaying

You just need to specify in your onclick event where you want the results to appear. You could use a panel for example and make it visible when you get the results.
This is not that hard to do.

Hi,
I have a gridview that has an xml datasource. When I click on the edit link next to a record then the fields are displayed in edit mode. There is a drop down list (in the edit mode) as well displaying all the store locations. The store locations are also populated from another xml datasource.
Here is my StoreLocators.xml file (which populates the gridview):
<Deposits>
<Deposit StoreLocator="Shoprite Paarl" DepositID="1" ClientCITNo="G32428932" BranchNo="300932" />
</Deposits>
Here is my StoreLocators.xml file:
<StoreLocators>
<StoreLocator StoreLocatorID="ShopriteAlberton" StoreLocatorName="Shoprite Alberton" />
<StoreLocator StoreLocatorID="ShopriteBloemfontein" StoreLocatorName="Shoprite Bloemfontein" />
<StoreLocator StoreLocatorID="ShopritePaarl" StoreLocatorName="Shoprite Paarl" />
</StoreLocators>
I populate the dropdown like this:
protected void rgDeposits_ItemCreated(object source, GridItemEventArgs e)
{
if (e.Item is GridEditableItem && e.Item.IsInEditMode)
{
DropDownList ddl = (DropDownList)e.Item.FindControl("rcStoreLocators");
ddl.DataSource = dsStoreLocators;
ddl.DataTextField = "StoreLocatorName";
ddl.DataValueField = "StoreLocatorID";
}
}
<EditItemTemplate>
<asp:DropDownList ID="rcStoreLocators" SelectedValue='<%# Eval("StoreLocatorID")%>' runat="server" />
</EditItemTemplate>
Error that I get:
DataBinding: 'System.Web.UI.WebControls.XmlDataSourceNodeDescriptor' does not contain a property with the name 'StoreLocatorID'.
So when the row goes into edit mode, I need the Shoprite Paarl to be selected as the default value. How do I do this?
Thanks
Brendan

Can you set the value to 0 in the .net code
|
|
|
|
|
Where do you want me to set this code?
|
|
|
|
|
In your c# when the dropdownlist is created
|
|
|
|
|
Check the original message I changed it. Please help with some C# code.
|
|
|
|
|
check this out it shows how to bind to a radiobuttonlist which is basically the same as binding to a dropdown

Hi,
I am redirecting my page with query string (UserId is passed as query string). User 'A' has the rights to access the new page. He enterred into that page and he does access. UserId of 'A' is passed as query string. He do not change the query string at the address bar. Now, 'A' can access the page by giving other User's Id after entering into this page. I want to make that address bar as read only after loading this page.
Is it possible?.
By mean time, I am checking the user id in the page load itself, if it false, I am redirecting into main page. Pls help.

You cant make the url bar read only, you could hide it and open a new window without it showing but the user can still find a way to by pass this. Best to not show the query string at all in the URL and to hide it instead.
There are lots of articles on hiding query string values when trasnferring them via url

Thank you for your reply.

How to hide the query string? I've read that this is the main disadvantage of qry string. Otherwise, Qry string should be encrypted and decrypted. I dont have any other idea. If u know that how to hide or If you have any articles link, Pls send me...tnx in adv.

If the information you are hiding is sensitive then its best to just use sessions

You can't make the address bar read only as ASP.NET don't have any control over the programs installed on the client machine. Your best bet is to validate the query string before processing.
I assume you are keeping currently logged in users id in session named "id". So in the page load check current user is authorized to see this page, something like
if(Session["id"] != NULL && Session["id"].ToString() != Request.QueryString["id"])
{
Response.Redirect("NotAuthorized.aspx");
}The above code will redirect to "NotAuthorized.aspx" if the id passed is not the current user. So user "A" can't pass some other id to see their details.
If you have many pages like this, I would prefer to create a base class and derive all your pages from it. So the checking can be automated.

I have a gridview that has some prices that is dispayed as strings.
In the database these prices are nvarchar datatype.
I need to sort them in the gridview as numbers because they are not sorted correctly as strings but at the moment I can't change this datatype in the database. So is there any workaround to sort this column as numbers? how?
|
|
|
|
|
Wouldn't you just convert the string to an int, if so Convert.ToInt32...something like that maybe
|
|
|
|
|
how can I do that?
do I have to do it inside the sorting event??
How..details plz.
thanks
