Forms Data Controls :: Showing Picture From Grid?
Sep 9, 2010
I have a grid view with some date [URL] I have column 'Zdjecie' with picture url and last column with camera button.
I wish that after clicking on camera button from last column, picture of url from column 'Zdjecie' wil be displayed.
I have atached event like this to clicking on camera button:
protected void grvWojewodztwa_CustomButtonCallback(object sender, DevExpress.Web.ASPxGridView.ASPxGridViewCustomButtonCallbackEventArgs e)
{
if (e.ButtonID != "ShowPicture")
return;
string vrlUrl = grvWojewodztwa.GetRowValues(e.VisibleIndex, "ob_zdjecie_link");
}
and i debugged it and vrlUrl is really picture url, but how to show this picture in new window or popup?

Before I get too involved in this new page, I want to besure I am going to go about it the correct way.
What is needed is a grid of some sort. The query returns groups of records, every two records are related and I need to insert a summary line after each pair of records.
Company 1 current
Company 1 previous
*insert a summary of the currency amounts displayed with the two records.
Company 2 current
Company 2 previous
*insert a summary of the currency amounts displayed with the two records.
.
. and so on
What data control should I use to do this (a girdview, datagrid, listview??, something else?) I am running VS. 2008.
I was given a summary sample on a previous post: [URL] But I want to be sure this is what I should actually use.

In one page I have image controls that are showing pics from the web site. This works fine but sometimes, and randomly some pics are not shown. I guess this issue could happen because Im using the IIS 5.1 in my development enviroment and it could be denying some requests. Anyway, I dont know exactly what is happening, so i request help of those who have workaround this fixture.

using asp.net/vb.net 2005. when I am in VS and I run the application I have a .net Image control where I am displaying an image programmatically and when I run this in VS all works well, the image displays.
I have the site setup in IIS now on the dev server however the problem is when I run this program from there, just navigating to the [URL] then I can run the program and not getting any exception, however I am not seeing the image when I click the button to view the image. The code is something like this: [Code]....
again this shows ok when I am in the application in vs.net in debug mode but not showing at all when I just open a broswer window and view it as a user would, has anyone seen this before?

I have this code to insert a picture from database into an ImageControl on my ASP.NET form:
strConnString = "server=" + Server + ";database=" + DataBase + ";UID=" + UID + ";password=" + PASS + ";";SqlConnection MyConnection = new SqlConnection(strConnString);SqlCommand MyCommand = new SqlCommand("SELECT Pic FROM MEN WHERE ID=5", MyConnection);MyConnection.Open();SqlDataReader MyReader = MyCommand.ExecuteReader();if (MyReader.Read()){ byte[] m_MyImage = (byte[])MyReader["Pic"]; Response.BinaryWrite(m_MyImage);}
And I have this ImageControl on the form:
<asp:Image Width="88" Height="100" Runat="server" ID="m_Image" NAME="m_Image" />
but when I run the code, I see the picture big on the screen and not in my ImageControl.
i also put this in the form_load:
m_Image.ImageUrl = "MyPhoneBook.aspx?m_Image";my control is: m_Imagemy control ID is: m_Imagemy namespace is MyPhoneBook

I had a problem before with GridView displaying picture and it was solve as post [URL] shows. I am trying to apply the same coding to another GridView with a different configuration and I am having a hard time making the adaptation. May someone take a look at it. What I am trying to add to this GridView is code as:
DataImageUrlFormatStringl='<%# IIF(System.IO.File.Exists(Server.MapPath(string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"))), string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"), "~/UploadedImagesClassifieds/NoPicture.gif")

Have a GridView with a templated select button hidden and using
e.Row.Attributes.Add("onclick",Page.ClientScript.GetPostBackEventReference(this.grdMaster, "Select$" + e.Row.RowIndex.ToString())); to select a row .
When user like to update the datasource he will select one row from gridview then in selected indexchanged event i would display the selected row values beneath the form under the grid , Then user will update the contents displayed from grid and click an update button which is outside the grid . After updating the displayed row , i got to get the values of the next row in the grid and display them for next updation , i'e if users maually selects row 3 from grid then he can update the values using the update button and then on update click itself i'll have to display next row contents of row 4 and this process could go on .

I have Parent/Child Grid (also called Nested Grids).
Parent Grid (PG) :: PG has two template fields. 1st template field has "Category ID" and 2nd template has Child Grid
Child Grid (CG) :: CG is populated in PG's RowDataBund event based on "Category ID". In CG's DataBound event, I am doing something which I need to display in CG's footer row.
Problem :: In the footer row of each CG, I have to show the "Category ID" which is in PG' row. How can I get hold of the PG's row which hascurrent nested grid (there will 'n' child grids, one for each 'Category ID' in the PG ) so I can read the "Category ID"
I was thinking if I could do something (DataBound event of CG) like this..
string catId = ChildGrid.Parent[get the index of the current row in PG].Cells[0].Text;

I do a gridview code that when displaying the information that come from the database is not showing any error at all, but is not displaying the right picture. The problem, I think, is that the (Eval("....") is not reading the values that are coming from the DataKeysNames. Due to this the right pictures are not displayed. But in another column, just for testing purposes I was able to display the values from DataKeysNames with the Eval. So I do not know what is going on and to make worse browser is not giving me any error. So, this is the line that is not processing, reading or executing well:
ImageUrl='<%# IIF( (Eval("TUDTIWasItemUpgraded")) = "Yes", string.Format("~/Images/ItemUpgradedTo.gif"), string.Format("~/Images/ItemNoUpgradedYet.gif") ) %>'

Dear all; I have a gridview as follows below
ID ZONE
A AFRICA
B NORTH AMERICA
now, i would like to add a little picture icon on the leftmost side of the gridview, that would allow a user to click on it...which will indirectly bring up a pop-up screen. In the pop-screen, i would like to add a textbox and a button to it, in which the user will be able to use to make an update to a field ID in the gridview.
