Loading from a Database

In addition to loading a document from a file, a document can be loaded from a database.

In web.config:

Add the connection string for your database. Set %DATABASE_NAME% to your database name.

	Copy Code
<connectionStrings> <add name="SqlImageProviderConnection" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=\|DataDirectory\|\%DATABASE_NAME%;Integrated Security=True;User Instance=True" /> </connectionStrings>

Copy Code

<connectionStrings>

   <add name="SqlImageProviderConnection" connectionString="Data
     Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\%DATABASE_NAME%;Integrated Security=True;User Instance=True" />

</connectionStrings>

Add the database to the list of providers (the code below is one very long line):

	Copy Code
<add name="SqlImageDataProvider" type="ImageGear.Web.DataProviders.SqlImageDataProvider,ImageGear.Web.Services" connectionStringName="SqlImageProviderConnection" sqlCommand="SELECT ImageData FROM dbo.ImageStore WHERE [Image_key] = @Image_key" sqlCommandType="Text" sqlImageDataField="ImageData" sqlParameter="@Image_key" paramKeySqlDbType="UniqueIdentifier" paramKeyLength="36" cachingEnable="false" sqlCacheDependencyNeeded="false" initSqlCacheDependency="false" maxImageSizeToCache="512" cachingTimeLimit="5" sqlArtReadCommand="SELECT Annotations FROM dbo.ImageStore WHERE [Image_key] = @Image_key" sqlArtReadCommandType="Text" sqlArtUpdateCommand="UPDATE dbo.ImageStore SET Annotations = @Annotations WHERE [Image_key] = @Image_key" sqlArtUpdateCommandType="Text" sqlArtDataField="Annotations" sqlArtParameter="@Annotations" />

Copy Code

    <add name="SqlImageDataProvider"
type="ImageGear.Web.DataProviders.SqlImageDataProvider,ImageGear.Web.Services" connectionStringName="SqlImageProviderConnection"
sqlCommand="SELECT ImageData FROM dbo.ImageStore WHERE [Image_key] = @Image_key" sqlCommandType="Text" sqlImageDataField="ImageData"
sqlParameter="@Image_key" paramKeySqlDbType="UniqueIdentifier" paramKeyLength="36" cachingEnable="false" sqlCacheDependencyNeeded="false"
initSqlCacheDependency="false" maxImageSizeToCache="512" cachingTimeLimit="5" sqlArtReadCommand="SELECT Annotations FROM dbo.ImageStore
WHERE [Image_key] = @Image_key" sqlArtReadCommandType="Text" sqlArtUpdateCommand="UPDATE dbo.ImageStore SET Annotations = @Annotations
WHERE [Image_key] = @Image_key" sqlArtUpdateCommandType="Text" sqlArtDataField="Annotations" sqlArtParameter="@Annotations" />

In Default.aspx, use openPage with the database provider:

	Copy Code
_ctrlView.openPage({ documentIdentifier: 'SqlImageDataProvider:6b29f53a-1e1b-446b-9b3b-9d234452f3e2', pageNumber: 1, viewFitType: ImageGear.Web.UI.FitType.ActualSize });
