Hi nena,

I hope this helps.

string Value;
string Exists="Exists";
Value= Datagrid1.Rows[1].Cells[1].Value.ToString();
if (Value=="0")
Datagrid1.Rows[1].Cells[1].Value = Exists;

be careful of the cell that you are working on. But it should work.
You can use a for loop for the rows and the columns. If you are searching in both rows and and columns for the value 0 then use something like this.

string Value;
string Exists="Exists";
for(int i=0; i<LoggerDatagrid.Columns.Count; i++)
{
for(int j=0;j<LoggerDatagrid.Rows.Count;j++)
{
Value= Datagrid1.Rows[j].Cells[i].Value.ToString();
if (Value=="0")
Datagrid1.Rows[j].Cells[i].Value = Exists;
}
}

hope it works.

Hi Keshav,

This works only if the original data given to the DataGrid was string , my main problem is that the column I need to edit its value is Short in the DataBase.
Therefore each type I pass string to this Column an Expection is throw Input is not in the correct form, That's way i was trying to convert string to int16 but still I can't do it.
This is so annoying to me , I don't want to change the field in the DataBase all I need is to change the Display instead of "0" to a string "Exists".

Hope i made it clear this time. Waiting for your help

Thanks a lot

I can't really shake a solution out of my sleeve, but I know a workaround that I often use.
Somewhere in your application you are probably using a Stored Procedure, or a SQL Query.

SELECT * FROM table

you could change it to this

 <br />
(SELECT [Name], 'Exists' <br />
FROM [Table]<br />
WHERE [Field] = 0)<br />
<br />
UNION<br />
<br />
(SELECT [Name], [Field]<br />
FROM [Table]<br />
WHERE [Field] <> 0)<br />

Another option would be to add a new column to your dgv, and place it in place of the other one, and populate it with the desired values.

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />
}

Int16 Value;
string Exists="Exists";
for(int i=0; i<LoggerDatagrid.Columns.Count; i++)
{
for(int j=0;j<LoggerDatagrid.Rows.Count;j++)
{
Value= (Int16)Datagrid1.Rows[j].Cells[i].Value.ToString();
if (Value=='0')
     Datagrid1.Rows[j].Cells[i].Value = Exists;
}
}

please check if this works.

If Windows XP, open a CMD prompt and type:

C:\WINDOWS>sc query type= driver

Make sure you put in the space between type= and driver.

Could you specify a little clearer what you are looking for?

Are you talking about actual dictionaries, with words and explanations or translations?
Or are you talking about the Dictionary class...?

Visual Studio can't evaluate this, can you?

public object moo<br />
        {<br />
__get { return moo; }<br />
__set { moo = value; }<br />

Showing a "Image" in a Datagrid

Nooie20-Mar-07 12:48

20-Mar-07 12:48

Hi all,

I am trying to show a "Image" in a DataGrid.
I have a new class I created that has 3 properties that are string and one that is of type image.
I create an Array of this class, and make the DataGrid source the Array.

But the image column comes up as a red cross in a white background, i.e. its not an image.

Can anyone give me some idea of best practice to show an image in a DataGrid please?

Regards

Tony

Hi Tony,

hope the following code works.

private void DataGrid1_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
System.Web.UI.WebControls.Image anImagine ;
if(e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Item )
{
anImagine = ((System.Web.UI.WebControls.Image)e.Item.Cells[1].Controls[1]); anImagine.ImageUrl="icons/" + e.Item.Cells[0].Text.ToString() + ".gif";
}
}

When you create strings special characters require an escape sequence. Any unicode character can be escaped by using \u and the unicode value, \uFEFF is one I am using because of some pdf issue. Newlines are \n tabs are \t a \ is \\.

Transfering values (Global variable)

20-Mar-07 11:21

Good evening everyone,
I have a feeling it's a silly question Unsure | :~

but how can you transfer a variable from one object to another without having to create another instance of these objects.. say I have two open forms and I want to pass a value entered in one form to the other one.

Thanks a million Rose | [Rose]
